String Validator Solution
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).
>>> print 'ab123'.isalnum()
True
>>> print 'ab123#'.isalnum()
False
str.isalpha()
This method checks if all the characters of a string are alphabetical (a-z and A-Z).
>>> print 'abcD'.isalpha()
True
>>> print 'abcd1'.isalpha()
False
str.isdigit()
This method checks if all the characters of a string are digits (0-9).
>>> print '1234'.isdigit()
True
>>> print '123edsd'.isdigit()
False
str.islower()
This method checks if all the characters of a string are lowercase characters (a-z).
>>> print 'abcd123#'.islower()
True
>>> print 'Abcd123#'.islower()
False
str.isupper()
This method checks if all the characters of a string are uppercase characters (A-Z).
>>> print 'ABCD123#'.isupper()
True
>>> print 'Abcd123#'.isupper()
False

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