string.split()

string.split(s[, sep[, maxsplit]]) → list of strings[source]

Return a list of the words in the string s, using sep as the delimiter string. If maxsplit is given, splits at no more than maxsplit places (resulting in at most maxsplit+1 words). If sep is not specified or is None, any whitespace string is a separator.

(split and splitfields are synonymous)
