pandas.core.strings.StringMethods.match

StringMethods.match(pat, flags=0, **kwargs)

Deprecated: Find groups in each string using passed regular expression. If as_indexer=True, determine if each string matches a regular expression.

Parameters :

pat : string

Character sequence or regular expression

case : boolean, default True

If True, case sensitive

flags : int, default 0 (no flags)

re module flags, e.g. re.IGNORECASE

na : default NaN, fill value for missing values.

as_indexer : False, by default, gives deprecated behavior better achieved

using str_extract. True return boolean indexer.

Returns :

matches : boolean array (if as_indexer=True)

matches : array of tuples (if as_indexer=False, default but deprecated)

Notes

To extract matched groups, which is the deprecated behavior of match, use str.extract.
