Adding functions in a list and calling them according to index
If you don't add () at the end you are not calling the function you are just referencing it by name. then you can iterate over it like any other value. def add(a, b): return a + b def subtract(a, b): return a - b def multiply(a, b): return a * b operations = [add, subtract, multiply] x = 5 y = 3 for f in operations: result = f(x, y) print(result) More on reddit.com

When a function reaches a return statement, it stops executing and sends the result back: ... def get_greeting(): return "Hello from a function" message = get_greeting() print(message) Try it Yourself » ... If a function doesn't have a return statement, it returns None by default. Function definitions cannot be empty. If you need to create a function placeholder without any code, use the pass statement: ... The pass statement is often used when developing, allowing you to define the structure first and implement details later.

November 4, 2025 - Through the number of arguments passed to the function, we can control where that sequence of numbers will begin and end, along with the difference between two consecutive numbers in the series. Python range() function is often used to iterate through a sequence using a for or while loop. Python’s reduce() function implements a mathematical technique called folding or reduction. This technique involves reducing a list of items to a single cumulative value.
