# 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 functionstarts_with_c_list = filter(starts_with_c, people)print starts_with_c_list# prints ['Charlie', 'Connie']
