String_Validators.py

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

# Input Format

# A single line containing a string .

# Constraints


# Output Format

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

# Sample Input

# qA2
# Sample Output

# True
# True
# True
# True
# True
