String Validators

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

Task

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.

Input Format

A single line containing a string S.

Constraints

0 ≤ len(S) ≤ 1000

Output Format

In the first line, print True if S has any alphanumeric characters. Otherwise, print False.
In the second line, print True if S has any alphabetical characters. Otherwise, print False.
In the third line, print True if S has any digits. Otherwise, print False.
In the fourth line, print True if S has any lowercase characters. Otherwise, print False.
In the fifth line, print True if S has any uppercase characters. Otherwise, print False.

Sample Input

qA2

Sample Output

True
True
True
True
True

Solution:

if __name__ == '__main__':
    s = input()

    is_alphanumeric = False
    is_alphabetical = False
    is_digits = False
    is_lowerChar = False
    is_upperChar = False

    for i in range(len(s)):
        substr1 = s[i:len(s)]
        substr2 = s[0:i]

        if substr1.isalnum() or substr2.isalnum():
            print(f"{substr1} ---- {substr2}")
            is_alphanumeric = True

        if s[i].isalpha():
            is_alphabetical = True

        if s[i].isdigit():
            is_digits = True

        if s[i].islower():
            is_lowerChar = True

        if s[i].isupper():
            is_upperChar = True


    print(is_alphanumeric)
    print(is_alphabetical)
    print(is_digits)
    print(is_lowerChar)
    print(is_upperChar)
