str.
isupper
() → ks.Series¶ Check whether all characters in each string are uppercase.
This is equivalent to running the Python string method
str.isupper()
for each element of the Series/Index. If a string has zero characters, False is returned for that check.Examples
>>> s = ks.Series(['leopard', 'Golden Eagle', 'SNAKE', '']) >>> s.str.isupper() 0 False 1 False 2 True 3 False dtype: bool
