pyspark.pandas.Series.str.isalpha#

str.isalpha()#

Check whether all characters in each string are alphabetic.

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

Examples

>>> s1 = ps.Series(['one', 'one1', '1', ''])
>>> s1.str.isalpha()
0     True
1    False
2    False
3    False
