pandas.Series.str.isdecimal#

Series.str.isdecimal()[source]#

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.

Returns:

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