- Functions aren’t special they can be
- assigned to variables
- added to lists
- passed to other functions
def area(radius):
area = 3.14159 * radius ** 2
return area
print area(1)
a = area
print a(1)
def diameter(radius):
return radius * 2
functions = [area, diameter]
for function in functions:
print function(2)
def do_all(func, values):
result = []
for value in values:
temp = func(value)
result.append(temp)
return result
values = [1, 2, 3]
print do_all(radius)
print do_all(diameter)
In fact, there’s actually a built-in Python function that does this: map().
