In many functions, you see a third argument flags. What are they and how do they work?

Flags allow you to control the regular expression engine. Because regular expressions are so powerful, they are a useful way of switching on and off certain features (e.g. whether to ignore capitalization when matching your regex).

For example, here’s how the third argument flags is used in the re.findall() method:re.findall(pattern, string, flags=0)

So the flags argument seems to be an integer argument with the default value of 0. To control the default regex behavior, you simply use one of the predefined integer values.

re.ASCII, re.A, re.DEBUG, re.IGNORECASE, re.I, re.LOCALE, re.L, re.MULTILINE, re.M, re.DOTALL, re.S, re.VERBOSE, re.X
