    I asked my friend from Morocco. He says the cat is asking for mouse flavored “Jumbo”. Jumbo is a brand of stock cubes which normally come in flavors like beef, chicken or lamb. The shopkeeper replies “que” in Spanish which means “what?”

    Thanks for sharing this. I took the time to read through the documentation of the re module. Here’s my review of the functions.

    Useful:

    • re.finditer returns an iterator over all Match objects
    • re.search returns the first Match object or None if there are no matches.
    • r'' use raw strings for patters so you don’t have to worry about backslashes
    • the optional flags argument modifies the behaviour (case insensitive, multiline)

    Utility:

    • re.sub replace each match in the string
    • re.split split a string by a regular expression

    The Match object:

    • match.groups(0) returns the portion of text matched by the pattern
    • match.groups(1) returns the first capturing group
    • match.groups(2) returns the second capturing group, and so on

    I don’t understand why these exist:

    • re.match like search, but only matches at the beginning of the string. why not just use ‘^’ or ‘\A’ in the pattern you pass to ‘search’?
    • re.fullmatch like ‘search’, but only if the full string matches. Why not just use ‘\A’ and ‘\Z’ in the pattern you pass to ‘search’?
    • re.findall Returns all matches. It seems like a shitty version of ‘finditer’. The function has three different return types which depend on the pattern you pattern you pass to the function. Who wants to work with that?
