Python regex string matching?
re.match implicitly adds ^ to the start of your regex. In other words, it only matches at the start of the string.
re.search will retry at all positions.
Generally speaking, I recommend using re.search and adding ^ explicitly when you want it.
the docs is clear i think.
re.match(pattern, string[, flags])ΒΆ
If zero or more characters **at the beginning of string** match theregular expression pattern, return a corresponding MatchObject instance. Return None if the string does not match the pattern; note that this is different from a zero-length match.
