There are three types of Python functions:Ī) Python build-in functions: They come with Python itself and you can use them directly like print.ī) Python modules – They also come with Python but to use them, you need to import them from their parent space like ‘sin’, ‘cos’ etc.Ĭ) User-Defined Functions – Functions which a user can code themselves like finding the speed of a vehicle if we know the distance travelled in time.įunctions may take arguments to evaluate something. There are functions which can perform both the above activities also. Generally, a Python function performs two activities:Ī) Cause some effect – like print functionī) Evaluates some value – like sum, sin, cos which we will see later Python function is a piece of code that performs some action or causes some effect. Let’s put some attention and time to see what functions are: It takes the string as an input/argument and displays the string on the console.

Write a lot of Python code- The only way you can learn programming is by writing a lot of code.So print is a function that displays the desired result for you.
