Python Strings Challenges - String Validators Solution

Problem Statement

Python has in built string validation methods for basic data validation such as checking if a string is alphabetical, alphanumeric, digit etc.

str.isalnum()
Check if all characters of string are alphanumeric (a-z, A-Z and 0-9).

>>> print 'ab123'.isalnum()
True
>>> print 'ab123#'.isalnum()
False

---

str.isalpha()
Check if all characters of string are alphabetical (a-z and A-Z).

>>> print 'abcD'.isalpha()
True
>>> print 'abcd1'.isalpha()
False

---

str.isdigit()
Check if all characters of string are digit (0-9).

>>> print '1234'.isdigit()
True
>>> print '123edsd'.isdigit()
False

---

str.islower()
Check if all characters of string are lowercase characters.

>>> print 'abcd123#'.islower()
True
>>> print 'Abcd123#'.islower()
False

---

str.isupper()
Check if all characters of string are uppercase characters.

>>> print 'ABCD123#'.isupper()
True
>>> print 'Abcd123#'.isupper()
False

---

Task

You are given a string S.
Your task is to find if string S contains, alphanumeric characters, alphabetical characters, digits, lowercase and uppercase characters.

Input Format

Single line containing, string S.

Constraints

0<len(S)<1000

Output Format

In First line, print True if S has any alphanumeric character, otherwise print False.
In Second line, print True if S has any alphabetical character, otherwise print False.
In Third line, print True if S has any digits, otherwise print False.
In Fourth line, print True if S has any lowercase character, otherwise print False.
In Fifth line, print True if S has any uppercase character, otherwise print False.

Sample Input

qA2

Sample Output

True
True
True
True
True

Solution:

import sys
if sys.version_info[0]>=3: raw_input=input
s=raw_input()
for e in ['isalnum','isalpha','isdigit','islower','isupper']: print(any(getattr(c,e)() for c in s))
