Let us suppose you wish to write a Python function that returns the square of a number like so: defsquare(x):return(x*x)print(square(5)) The output will be: 25 You can also write a function to compute cubes like: defcube(x):return(x*x*x)print(cube(5)) ...
In Python, there's no "null" keyword. However, you can use the "None" keyword instead, which implies absence of value, null or "nothing". It can be returned from a function in any of the following ways: By returning None explicitly; By returning an empty return; By returning nothing...

To carry out that specific task, the function might or might not need multiple inputs. When the task is carried out, the function can or can not return one or more values. There are three types of functions in Python: Built-in functions, such as help() to ask for help, min() to ...
However, in real-world programs, we use the return keyword to return back the result of the function. The return keyword allows us to store the result of the function in a variable. Unlike many other languages, we do not need to declare a return type of the function explicitly. Python ...
Create a Function If you like to have a function where you can send your strings, and return them backwards, you can create a function and insert the code from the example above. Example defmy_function(x): returnx[::-1] mytxt =my_function("I wonder how this text looks like backwards...
To support functional programming, it’s beneficial if a function in a given programming language can do these two things:Take another function as an argument Return another function to its callerPython plays nicely in both respects. Everything in Python is an object, and all objects in Python...
In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.
