Python Function Tutorials

Python functions.

So lets assume you know how print works.
For example,
print ("Hello world")
OUTPUT
Hello world

---

First to use functions you need to define a function.
This can be done like this
def
def stand for define. After you define the name of the function it must be followed by a :
for example,
def functionname:

In my situation i'm going to define the function name to helloworld.
Example:
def helloworld:

CONGRATULATIONS, you defined the function however, you're not done yet. You need to add code to the function. Because I want it to output "Hello world" when it is called on I will add it.
Example:
def helloworld:
print("Hello world")

OUTPUT:
(Nothing)

As you can see this code outputs nothing, this is because you have not called on the function to do this you must write
functionname() on your code where you want it to appear.
Example:
def helloword:
print("Hello world")
helloworld()

OUTPUT:
Hello world
