Thank you and gor coding large scale things is this required.

Answer 2

Python comes with several pre-defined functions. Usually during the development process, you will be creating your own for whatever use you require them for.

All 'def' does is defines a new function. Consider it a shorthanded notation of 'definition'. Once you define a function, you give it a name. So let's say:

def newfunc(): [Remember that the parentheses are mandatory]

Now, you need to decide what you want the function to do. Let's say we want the function to print out "spam" (pretty standard), in that case we add:

def newfunc():
print("spam")

Finally, in order to execute this code in our project we simply call on the function as such:

newfunc()

Answer 3

def name():
print("lalala")
name
Output:
lalala
