Creating Function on Python Programming Language

Python let’s you create functions of your own. Function that you create will be used for the one problem. So, if there are two functions will be used two problems. If there are three functions will be used for three problems, and furthermore.
Creating your own functions offer you many advantages. One of them is that it allows you to break up your code , manage you code, and so on. By making functions, you can make formulas with your own name or others, it is up to you. I think many other advantages.
How to make function in Python ? How we create that ? See the formulas below.

def yourOwnName(var) :
    instructions
    return result

To understand more about this, I give you some examples below. Please read slowly and understand step by step :

See the other example below :

Explanations :

• The example above, in sayGreeting function isn’t using return but using print (It is allowed by Python).
• In circle function, you have to import pi = 3,14 from math modul.
• In factorial function, it is recursive. What’s the meaning of recursive ? If you see the factorial function, there is instruction with name “factorial(n-1)”. The name of instruction is same with the name of function. So, we can conclude that it’ll be called when a function call instruction itself.

I think this topic is not difficult to understand, so you can improve your skill by using functions. You can create your own functions, and you can solve many problems with your own functions.I think enough for today, I will continue my writing about other topics.
