ITS320 Module 2 Option 1 Creating a Python Application for string validation

Description

Option #1: Creating a Python Application
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()
FalseSAMPLE
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
Assignment Instructions:
Write a Python program that performs the following tasks:
1. Read from the console an arbitrary string S of length less than 50 characters.
2. In the first output line, print True if S has any alphanumeric characters. Otherwise, print False.
3. In the second line, print True if S has any alphabetical characters. Otherwise, print False.
4. In the third line, print True if S has any digits. Otherwise, print False.
5. In the fourth line, print True if S has any lowercase characters. Otherwise, print False.
6. In the fifth line, print True if S has any uppercase characters. Otherwise, print False.
7. Develop Python code that implements the program requirements.
