python sorted lambda

a = ["tim", "bob", "anna", "steve", "john"]

# sorts the list by the first letter of each name
b = sorted(a, key=lambda x : x[0])
# x = each of the values in the list a

# sorts the list by length FIRST, then alphabetical order SECOND
c = sorted(a, key=lambda x : (len(x), x))

sort() with lambda

lst = ['id01', 'id10', 'id02', 'id12', 'id03', 'id13']
lst_sorted = sorted(lst, key=lambda x: int(x[2:]))
print(lst_sorted)
