Hi, I just begin to learn Python. I do not see the usefulness of '*' in its description below:
The first metacharacter for repeating things that we'll look at is *. * doesn't match the literal character *; instead, it specifies that the previous character can be matched zero or more times, instead of exactly once. For example, ca*t will match ct (0 a characters), cat (1 a), caaat (3 a characters), and so forth. It has to be used with other search constraints?
