Question

What are the common built-in data types in Python?

Answer 1

There are several built-in data types in Python. Although, Python doesn't require data types to be defined explicitly during variable declarations but type errors are likely to occur if the knowledge of data types and their compatibility with each other are neglected. Python provides type() and isinstance() functions to check the type of these variables. These data types can be grouped into the following catetgories-

• None Type
  None keyword represents the null values in Python. Boolean equality operation can be performed using these NoneType objects.
