A variable is a container of data in a

computer’s memory where the computer stores 4 2.5
the different types of data and this could be

Variable (data containers) we name them so

we can call them in our program where it is
necessary.

Data can be of any type like text, numbers,
integers, etc. A variable can store values only in one

data type either it could be numeric or string. Python
has no command for declaring a variable.
