Day 6

https://docs.python.org/2/library/

Functions use arguments

Print(variable) for example
In this example

1. def spam():
2.     eggs = 99
3.     return eggs
4. 
   
5. number = spam()
6. print (number)

Line 6 needs the argument (number)  or it will never print 99, you will get an error.

Global and local scope.

Change a global variable with a local scope variable 

1. def spam():
2.        global eggs
3.        eggs = 'Hello'
4.        print = (eggs)
5. 
   
6. 
   
7. eggs = 42
8. spam()
9. print(eggs)
