pandas.Series.str.isdecimal

Check whether all characters in each string are decimal.

This is equivalent to running the Python string method str.isdecimal() for each element of the Series/Index. If a string has zero characters, False is returned for that check.

return

Series or Index of bool Series or Index of boolean values with the same length as the original Series/Index.

Limitations

Series elements are expected to be Unicode strings. Elements cannot be NaNs.

Examples

Check whether all characters in each string are decimal.

import pandas as pd
from numba import njit


@njit
def series_str_isdecimal():
    series = pd.Series(['23', '³', '⅕', ''])
    out_series = series.str.isdecimal()

    return out_series  # Expect series of True, False, False, False


print(series_str_isdecimal())

$ python ./series/str/series_str_isdecimal.py
0     True
1    False
2    False
3    False
dtype: bool
