In this example we use two variables, a and b, which are used as part of the if statement to test whether b is greater than a. As a is 33, and b is 200, we know that 200 is greater than 33, and so we print to screen that "b is greater than a". Indentation. Python relies on indentation (whitespace at the beginning of a line) to define scope in ...

Python Collections (Arrays) There are four collection data types in the Python programming language: List is a collection which is ordered and changeable. Allows duplicate members. Tuple is a collection which is ordered and unchangeable. Allows duplicate members. Set is a collection which is unordered, unchangeable*, and unindexed. No duplicate ...
Python is an object-orientated language, and as such it uses classes to define data types, including its primitive types. Casting in python is therefore done using constructor functions: int() - constructs an integer number from an integer literal, a float literal (by removing all decimals), or a string literal (providing the string represents a whole number)

Python Variables - GeeksforGeeksHow to Use Type Annotations for Variables in Python? Type annotations in Python provide a way to specify the expected type of a variable. They do not enforce type checking at runtime but can be used by static type checkers, IDEs, and linters to help catch type-related errors. Example:
