# Suppose you have a list of people's first names. You want to reduce the list down to only those people whose first names start with "C". people = ['Amy', 'Alice', 'Bobby', 'Charlie', 'Connie', 'David'] # You would create a callback function that would look something like this: def starts_with_c(name): if name[0] == "C": return True return False # So then, you would run the filter function starts_with_c_list = filter(starts_with_c, people) print starts_with_c_list # prints ['Charlie', 'Connie']
