In Python, a variable is a named storage location that holds a value. When you create a variable, you can specify the name and value that you want to store in it.

The value can be of any data type, such as a string, integer, or float. You can then access the value stored in a variable by referencing its name.

Imagine that you have a box with a label on it that says "my_favorite_color". Inside the box, you can put a piece of paper with the name of your favorite color written on it, such as "blue" or "green". This piece of paper is like a value that you can store in a variable.

In Python, you can create a variable like this:

my_favorite_color = "blue"

In this example, my_favorite_color is the name of the variable, and "blue" is the value that is stored in it.

You can then access the value stored in the variable by referencing its name:

print(my_favorite_color) # Output: blue

In this case, the print function is used to display the value of the my_favorite_color variable on the screen. The output will be "blue", which is the value that was stored in the variable.

You can also change the value stored in a variable by assigning a new value to it:

my_favorite_color = "green" print(my_favorite_color) # Output: green

In this example, the value of the my_favorite_color variable is changed from "blue" to "green", and then the new value is displayed using the print function. The output will be "green", which is the updated value of the variable.
