pandas.Series.str.endswith — pandas 2.3.3 documentation#pandas.Series.str.endswith

Series.str.endswith(pat, na=<no_default>)

Test if the end of each string element matches a pattern.

Equivalent to str.endswith().

Parameters:

pat: str or tuple[str, …]

Character sequence or tuple of strings. Regular expressions are not accepted.

na: scalar, optional

Object shown if element tested is not a string. The default depends on dtype of the array. For the "str" dtype, False is used. For object dtype, numpy.nan is used. For the nullable StringDtype, pandas.NA is used.

Returns:

Series or Index of bool

A Series of booleans indicating whether the given pattern matches the end of each string element.

Series.str.contains

Examples:

>>> s = pd.Series(["bat", "bear", "caT", np.nan])
>>> s
0     bat
1    bear
2     caT
3     NaN
dtype: str

>>> s.str.endswith("t")
0     True
1    False
2    False
3    False
dtype: bool

>>> s.str.endswith(("t", "T"))
0     True
1    False
