Python data types

In Python, None is a special constant that represents the absence of a value or a null value. It is an object of its own data type, the NoneType, and it is not equivalent to any other value or data type.

Type conversion in Python refers to the process of converting a value from one data type to another. This is a common task when writing code. It allows for more flexibility in how data is processed and ensures that operations between different types of data are error-free. Python performs some type conversions automatically, and also provides several built-in functions to convert between different data types.

A Boolean is a data type that has either one of two values representing a conceptual "true" or "false". Booleans are named after the mathematician George Boole, who was a pioneer of mathematical logic. In programming, they are used for decision-making, (i.e. to determine whether the computer should do something or not.

Numbers are a fundamental aspect of computer programming. Python provides robust support for numeric operations and data types. This lesson covers the three built-in numeric types available in Python: integers, floating-point numbers, and complex numbers.

A Python string is a sequence of text characters. Strings are among the most commonly used data types in Python, and essential for handling text data. Python strings are easy to use and in many ways, work like other Python collections data structures, such as lists and tuples, do. They can be considered ordered collections of individual characters.
