Defining a Function
Option 1:
def plus_five(x):
return x+5
plus_five(x)
Option 2:
def five_plus(x):
result = x+5
return result
plus_five(x) |
Defined function name, returned function form, executed function. We can print text as well as results by using the print function
Composite Functions
def wage(hrs):
return 25*hrs
def with_bonus(hrs):
return 50 + wage(hrs)
wage(40), with_bonus(40)
(1000, 1050)
|
