Python supports various data types in order to store different types of data. This includes integers, floats, strings, and more. Each data type has specific properties and functions that can be used on them.
For example, strings can be concatenated while floats can be converted to integers.
Python has a variety of data types that can be used to store information. The most common data types are integers, floats, strings, and booleans. Integers are whole numbers that can be positive or negative.
Floats are decimal numbers. Strings are sequences of characters and can be represented with single quotes (‘ ‘) or double quotes (” “). Booleans are True or False values.
Python also has a few more complex data types, such as lists, tuples, dictionaries, and sets. These data types can be used to store more complicated information than the basic data types.
Python Data Types Check
Python is a programming language with many data types. In this article, we’ll go over different data types and how to check their type in Python.
First, let’s start with the most basic data type: the integer.
To check if a variable is an integer, we can use the isinstance() function. For example:
>>> var1 = 1
>>> isinstance(var1, int)
True
Now let’s try with a different data type, like a string.
We’ll create a new variable and see if it returns True when we check its type:
>>> var2 = “Hello”
>>> isinstance(var2, str)
True
We can also use the isinstance() function to check for multiple data types at once. For example, if we want to check if a variable is either an integer or a string, we can do this:
>>> var3 = “World”
>>> isinstance(var3, (int, str)) # Checks if var3 is either an int or str
Python Data Structures
Python is a high-level, interpreted, general-purpose programming language, created on December 3, 1989, by Guido van Rossum, with a design philosophy entitled, “There’s only one way to do it, and that’s why it works.”
In Python, data structures are very intuitive. The most basic data structure in Python is the list.
A list can be created by putting values inside of square brackets [ ]. Lists can contain any type of value (ints, floats, strings, etc.). Each value in the list is called an element.
Individual elements in a list can be accessed by their index. In Python indices start at 0.
Lists are mutable which means they can be changed after they are created.
To change an element in a list you use assignment (=). This will replace the element at that index with whatever you assigned it to. If you want to add an element to the end of a list you use the .
append() method.
Tuples are immutable lists. That means once they are created tuples cannot be changed unlike lists which are mutable .
Tuples use parentheses () instead of square brackets [ ] like lists .
Dictionaries store mappings from keys to values and these key-value pairs provide a structure for storing data similar to what arrays do in other languages although Dictionaries work with keys and not numbers like arrays usually do . Keys can be eitherimmutable types such as strings or tuples or mutable types such as lists but usually only immutable types are used as keys .
Values onthe other hand can be any type including mutable types like lists
How Many Data Types in Python
Python has a total of eight data types. These include the following:
- Integer
- Float
- Complex
- Boolean
- String
- Tuple
- List
- Dictionary
Each data type has a specific purpose and is used in different ways, depending on the situation and what you’re trying to accomplish. Let’s take a closer look at each one:
- Integer – whole numbers like 4, 7, 10, etc. They can be positive or negative, but they cannot have decimals points like floats do (we’ll get to floats next). You can perform mathematical operations on integers like addition, subtraction, multiplication, etc.
- Float – decimal numbers like 3.14159265359, 0.10000000003 ,-03932748523985723984 . Just like integers, you can perform mathematical operations on floats as well . One key difference between floats and integers is that you cannot convert a float into an integer without losing information (i . e . the decimal points will be dropped).
- Complex – these are actually two floating point numbers put together , one real and one imaginary . The imaginary number always has an ‘i’ after it , for example : 2 + 3i or 5i . You cannot perform mathematical operations on complex numbers by themselves , but you can if both complex numbers are converted to floats first .
- Boolean – this data type only has two values : True or False (written with a capital ‘T’ and ‘F’ ). Booleans are often used in programming to keep track of whether something is true or false so that the program knows what to do next . For example , if x = 5 and y = 10 , then x < y would evaluate to True and x > y would evaluate to False .
- String – sequences of characters like “hello” , “goodbye” , “I am 26 years old”. Strings can contain any letters , digits , punctuation marks , or spaces ; basically anything that can be typed on a keyboard .
Data Types in Python Pdf
Python has a variety of data types that it can use. These data types can be divided into three main categories:
- Immutable data types (cannot be changed): int, float, complex, bool, str, tuple, frozenset
- Mutable data types (can be changed): list, dict, set
- Specialized data types: bytes, bytearray, range Each of these data types has specific characteristics and functions that are associated with it.
Let’s take a closer look at each one. Ints are whole numbers that can be positive or negative. Floats are decimal numbers.
Complex numbers are made up of a real part and an imaginary part. Bools represent true or false values. Strings are sequences of characters enclosed in quotes.
Tuples are immutable lists enclosed in parentheses. Frozensets are unordered sets that cannot contain duplicate elements. Lists are mutable sequences of elements enclosed in square brackets [ ].
Dicts are mutable collections of key-value pairs enclosed in curly braces { } . Sets are unordered collections of unique elements enclosed in curly braces { } . Bytes and bytearrays represent sequences of bytes; ranges representsequences of integers with a start, stopand step value.
Python Data Types Journaldev
Python is a powerful programming language. It is very popular these days because it is easy to learn and has many modules that allow for robust programming. Python data types are an important part of understanding how the language works.
In this article, we will take a look at the different data types in Python and how they are used.
The most basic data type in Python is the integer. An integer is a whole number that can be positive, negative, or zero.
Integers are represented by the int keyword in Python.
The next basic data type is the float. A float represents a real number and is represented by the float keyword in Python.
Floats can be positive or negative, but they cannot be zero.
Another basic data type in Python is the string. A string is a sequence of characters and is represented by the str keyword in Python.
Strings can contain any characters, including letters, numbers, whitespace, and punctuation marks.
Python also has a boolean data type which can represent two values: True or False . The bool keyword represents this data type in Python .
Boolean values are often used in control structures to determine whether or not a certain condition has been met .
There are several otherdata types available in Python , but these four are the most basic . With these four data types , you can already do quite a lot with your programs .
Python Data Types Cheat Sheet
Python is a programming language with many data types. In this article, we will look at the most common Python data types.
The most common data type in Python is the integer.
An integer is a whole number, and can be positive, negative, or zero. We can use the function int() to convert other data types to integers.
The next most common data type is the float.
A float is a number with a decimal point. We can use the function float() to convert other data types to floats.
Another common data type is the string.
A string is a sequence of characters, and we can use the function str() to convert other data types to strings.
Python Data Types Size
Python’s data types are divided into two main categories: mutable and immutable. The size of a data type is the number of bits needed to store it in memory.
Mutable data types can be changed in place, without creating a new object.
The size of a mutable data type is the number of bits needed to store its value, plus any overhead required for internal bookkeeping. For example, an integer requires 32 bits to store its value, plus some additional overhead for housekeeping purposes.
Immutable data types cannot be changed in place.
When you need to change the value of an immutable object, you must create a new object with the desired value. The size of an immutable object is the same as that of a mutable object: the number of bits needed to store its value plus any overhead required for internal bookkeeping. However, because immutable objects cannot be changed in place, they typically require less memory overall than mutables ones: once an immutable object has been created, there’s no need to keep track of any changes that might occur to it later on.
Built-In Data Types in Python
Python has a number of built-in data types that it uses to represent information. The most common data types are integers, floats, strings, and Booleans. Python also has a complex data type, which is used to represent more complicated information.
Integers are whole numbers. They can be positive or negative, but they cannot have decimal points. Floats are numbers with decimal points.
They can be positive or negative as well. Strings are sequences of characters. They can be made up of any combination of letters, numbers, and punctuation marks.
Booleans are logical values that can only be True or False .
Complex values are created by combining two or more other values together. For example, you could create a complex value by combining an integer and a float: 3 + 4j .
This would create a complex number with a real part of 3 and an imaginary part of 4 . Complex values can be used in mathematical operations just like other values.
Python has a few other built-in data types that we won’t go into here.
These include lists , tuples , sets , and dictionaries .
What are the 4 Types of Data in Python?
Python has four main data types: integers, floating point numbers, strings, and Boolean values. Each data type has a specific purpose and is used in different ways.
Integers are whole numbers that can be positive or negative.
They are used to represent numeric values in Python programs. Floating point numbers are fractional numbers that can be positive or negative. They are used to represent real-world values like money or weight.
Strings are sequences of characters that can be used to store text information. Boolean values are either True or False and are often used to track the state of something in a program.
What are the 5 Data Types in Python?
Python has a number of data types that are built into the language. These are called native data types. Python also allows for creation of new data types, called user-defined data types.
The 5 native data types in Python are:
- integers
- floating point numbers
- complex numbers
- strings
What are the 7 Data Types?
The 7 data types are:

- Boolean
- Array
What are 3 Types of Python?
Python is a versatile language that you can use for building all sorts of applications. In this article, we’ll take a look at three different types of Python: CPython, Jython, and IronPython.
CPython is the most common type of Python.
It’s written in C, and it’s the reference implementation of the language. CPython is what you get when you download Python from python.org.
Jython is a version of Python that runs on the Java Virtual Machine (JVM).
It allows you to write Python code that interacts with Java code. Jython is used in a lot of places where Python and Java need to work together, like in some web applications.
IronPython is an implementation of Python that runs on .
NET and Mono. It’s used in a lot of places where Python and .NET need to work together, like in some software development tools.
How Many Data Types are in Python?
There are 8 data types in Python:
- -bool
- -int
- -float
- -str
- -list
- -tuple
- -dict
What are the 4 Main Data Types?
There are four main data types in computer programming: integers, floating-point numbers, characters and strings.
Integers are whole numbers, like 1,2,3 or -4,-5,-6. They can be positive or negative but they cannot have decimal points.
Integer arithmetic is very fast on most computers.
Floating-point numbers have decimal points, like 3.14159 or -2.71828. They can be positive or negative but the range of values is much larger than for integers.
Floating-point arithmetic is not as fast as integer arithmetic on most computers but it is adequate for many applications such as graphics and sound processing where accuracy is not critical.
Characters represent single letters of the alphabet, punctuation marks and other symbols like ‘A’, ‘%’ or ‘$’. Characters are usually stored in a byte (8 bits) but some systems use larger units such as 16 bits or 32 bits.
Characters from different alphabets need more than one byte to represent them so internationalization issues must be considered when designing character sets for use with computers. In addition to the standard ASCII character set there are many others in use including Unicode which supports virtually all of the world’s languages.
Strings are sequences of characters, like “Hello World” or “May the Force be with you”.
Strings are typically used to store text but they can also be used to store binary data like program code or image files (in this case they would usually be called “binary strings”). Most programming languages provide support for strings as a primitive data type and many also provide library functions for working with strings such as searching, concatenation and formatting..
