pandas.Series.str.match#

Series.str.match(pat, case=True, flags=0, na=None)[source]#

Determine if each string starts with a match of a regular expression.

Parameters:

patstr: Character sequence or regular expression.
casebool, default True: If True, case sensitive.
flagsint, default 0 (no flags): Regex module flags, e.g. re.IGNORECASE.
nascalar, optional: Fill value for missing values. The default depends on dtype of the array. For object-dtype, numpy.nan is used. For StringDtype, pandas.NA is used.

Returns:

fullmatch: Stricter matching that requires the entire string to match.
contains: Analogous, but less strict, relying on re.search instead of re.match.
extract: Extract matched groups.

Examples

>>> ser = pd.Series(["horse", "eagle", "donkey"])
>>> ser.str.match("e")
0   False
