Python has built-in string validation methods for basic data. It can check if a string is composed of alphabetical characters, alphanumeric characters, digits, etc.
str.isalnum()
This method checks if all the characters of a string are alphanumeric (a-z, A-Z and 0-9).
This method checks if all the characters of a string are alphanumeric (a-z, A-Z and 0-9).
>>> print 'ab123'.isalnum()
True
>>> print 'ab123#'.isalnum()
False
>>> print 'abcD'.isalpha()
True
>>> print 'abcd1'.isalpha()
False
>>> print '1234'.isdigit()
True
>>> print '123edsd'.isdigit()
False
>>> print 'abcd123#'.islower()
True
>>> print 'Abcd123#'.islower()
False
>>> print 'ABCD123#'.isupper()
True
>>> print 'Abcd123#'.isupper()
False

String Validators - Hacker Rank Solution
Check the string by using the methods: .isalpha(), .isalnum(), .isdigit(), .islower() and .isupper().
Problem Setter's code:
S = raw_input()
print any([char.isalnum() for char in S])
print any([char.isalpha() for char in S])
print any([char.isdigit() for char in S])
print any([char.islower() for char in S])
print any([char.isupper() for char in S])
ReplyDeletecorrect code for given problem
S = input()
print(any(char.isalnum() for char in S))
print(any(char.isalpha() for char in S))
print(any(char.isdigit() for char in S))
print(any(char.islower() for char in S))
print(any(char.isupper() for char in S))
yes for python3 >
Deleteraw_input is python2 you should know this lol
Shut up
