HackerRank String validators problem solution in python

In this String validators problem solution in python, 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.

You are given a string S.

Your task is to find out if the string S contains: alphanumeric characters, alphabetical characters, digits, lowercase and uppercase characters.

Problem solution in Python 2 programming.

S = raw_input()
print True if any(k in "0123456789" or k.lower() in "abcdefghijklmnopqrstuvwxyz" for k in S) else False
print True if any(k.lower() in "abcdefghijklmnopqrstuvwxyz" for k in S) else False
print True if any(k in "0123456789" for k in S) else False
print True if any(k in "abcdefghijklmnopqrstuvwxyz" for k in S) else False
print True if any(k in "ABCDEFGHIJKLMNOPQRSTUVWXYZ" for k in S) else False

Problem solution in Python 3 programming.

if __name__ == '__main__':
    s = input()
    print(any(a.isalnum() for a in s) )
    print(any(a.isalpha() for a in s) )
    print(any(a.isdigit() for a in s) )
    print(any(a.islower() for a in s) )
    print(any(a.isupper() for a in s) )

# Enter your code here. Read input from STDIN. Print output to STDOUT
S=raw_input()
a=0
for i in range(len(S)):
    if S[i].isalnum():
         a+=1
if a>0:
    print 'True'
else:
    print 'False'

a=0
for i in range(len(S)):
    if S[i].isalpha():
         a+=1
if a>0:
    print 'True'
else:
    print 'False'
