A Detailed Tutorial on Python Variables:
Our previous tutorial explained us about Python and its Installation process in detail.
In this tutorial, we will have an in-depth look at the Python Variables along with simple examples to enrich your understanding of the python concepts.
Read through our Entire Python Series for a clear understanding of the various concepts involved in Python.

Role and Importance of Variables in Python
Python Variables
A variable means holding a value or reserving memory location to store values. In variable, you can store any kind of values by using appropriate data types.
In Python, variables do not need a declaration to reserve memory space. The “variable declaration” or “variable initialization” happens automatically when we assign a value to a variable.
How to Declare and use a Variable
To declare a variable we use “=” to assign the value to a variable.
Example:
We will declare the following variable and print it.
Number= 25 Name = “Kiran” B= 3.5 print (Number) print(Name) print (B)
Re-declare a Variable
We can re-declare a variable at any point of time even after you have declared it once.
Example:
Name = Python print(Name)
Multiple Assignment
In Python, we can assign the same value to multiple variables at once.
Example:
x = y = z = "SoftwareTestingHelp" print (x) print (y) print (z)
We can also assign multiple values to multiple variables.
Example:
a, b, c = 5, 3.2, "Hello" print (a) print (b) print (c)
Hope you would have understood the concept of Python Variables in detail from this tutorial.
