Python

The Python ‘is’ Operator

The Python is operator determines whether two references (variables or literals) point to the same object in memory, i.e. whether they are the same object. The is operator is different from the equality operator ==, which checks whether the values of potentially two objects are equal.

Python Type Conversion

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.

Python Booleans

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.

Python Numbers

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.

Python Strings

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.
