So, your functions can return numeric values (int, float, and complex values), collections and sequences of objects (list, tuple, dictionary, or set objects), user-defined objects, classes, functions, and even modules or packages. The __init__() Function. The examples above are classes and objects in their simplest form, and are not really useful in real life applications. To understand the meaning of classes we have to understand the built-in __init__() function. All classes have a function called __init__(), which is always executed when the class is being initiated.

The functools module is for higher-order functions: functions that act on or return other functions. In general, any callable object can be treated as a function for the purposes of this module. The functools module defines the following functions: @functools.cache(user_function) ¶. Simple lightweight unbounded function cache.Python’s range acts as a built-in function, and is commonly used for looping a specific number of times in for-loops. Like many things in Python, it’s actually a Python type (or class), but when using it in a loop, … Python bool () Function. Every data type has a boolean value means it can be represented as True or False. The bool () function converts any data type into its boolean value. Example 0, False, [], (), {}, '', None, are all converted into False whereas any other data type will be converted into True. functions are first-class objects in python. you can pass them around, include them in dicts, lists, etc. Just don't include the parenthesis after the function name. Example, for a function named myfunction: myfunction means the function itself, myfunction() means to call the function and get its return value instead. –Python closure is a nested function that allows us to access variables of the outer function even after the outer function is closed. Before we learn about closure, let's first revise the concept of nested functions in Python.
