str.
isdigit
Check whether all characters in each string are digits.
This is equivalent to running the Python string method str.isdigit() for each element of the Series/Index. If a string has zero characters, False is returned for that check.
str.isdigit()
Examples
>>> s = ps.Series(['23', '³', '⅕', ''])
The s.str.isdecimal method checks for characters used to form numbers in base 10.
>>> s.str.isdecimal() 0 True 1 False 2 False 3 False dtype: bool
The s.str.isdigit method is the same as s.str.isdecimal but also includes special digits, like superscripted and subscripted digits in Unicode.
>>> s.str.isdigit() 0 True 1 True 2 False 3 False dtype: bool
The s.str.isnumeric method is the same as s.str.isdigit but also includes other characters that can represent quantities such as unicode fractions.
>>> s.str.isnumeric() 0 True 1 True 2 True 3 False dtype: bool
