Variables are one of the fundamental building blocks of programs written in Python. Variables hold data in memory. They have names, and they can be referenced by those names. Variables also have types, which sp

But in Python, variables aredynamically typedand not subject to thedata typerestriction. A variable may be assigned to a value ofone type, and then later, we can also re-assigned a value of adifferent type. Let’s see the example. Example var =10print(var)# 10# print its typeprint(t...
