List FunctionsΒΆ

Python has several functions that can take lists as inputs. We will present four such functions here.

  • len() returns the number of items in the list.

  • sum() returns the sum of the elements in a list. This only works on numerical lists.

  • max() returns the largest item in the list.

  • min() returns the smallest item in the list.

We will illustrate the use of these functions using the two lists below.

names = ['beth', 'drew', 'fred', 'chad', 'anna', 'emma']
sales = [126, 81, 135, 114, 163, 92]
# Find the length of the lists.
print(len(names))
print(len(sales))

# Sum the sales list.
print(sum(sales))
711
# Find min and max of names list.
print(min(names))
print(max(names))
anna
fred
# Find min and max of sales list.
print(min(sales))
print(max(sales))
