What is Variable in Python and How to Create Variables in Python | Python Tutorials
In Python, a variable is a named location in memory that stores a value. A variable is like a container that holds a value, and you can use a variable to refer to the value it holds. This allows you to use the same value in multiple places in your code, and to easily change the value if needed.
To create a variable in Python, you use the assignment operator (=) to assign a value to a variable. For example, the following code creates a variable named "my_var" and assigns the value "Hello, World!" to it:
Copy code
my_var = "Hello, World!"
Once you have created a variable, you can use it in your code by simply referencing the variable name. For example, the following code uses the "my_var" variable to print the value it holds:
Copy code
print(my_var)
This will print the message "Hello, World!" to the console. You can also use the value of a variable in expressions and calculations. For example, the following code uses the "my_var" variable to concatenate two strings:
Copy code
message = my_var + " This is a test."
print(message)
This will print the message "Hello, World! This is a test." to the console. As you can see, using variables in Python allows you to use the same value in multiple places in your code, and to easily change the value if needed.
