Well, now I've learned what def is good for. But what could I put in the
parenthesis of def foo():?
Of course self is always available, but what would maybe def
foo(number1): do? An error right? So I now repeat my self, what else
besides
>>> def foo(x):
... print x
...
>>> foo('hi')
hi
What goes in the brackets is simply the arguments that foo() works with.
>>>def foo(a,b):
... return a + b
>>> sum = foo(5,10)
>>>print sum
15
>>> conjun = foo("Hi ", "Dave")
>>>print conjun
Hi Dave
Good luck,
