Today we will try to work with Python Strings

Task1: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
Hint Function: isalnum(), isalpha(), isdigit(), islower(), isupper()

Task2:You are given a string and width . Your task is to wrap the string into a paragraph of width

Example:

String :ABCDEFGH, Max_width= 4

Output: ABCD
EFGH

Solution:

Task 1

    s = input()

    #alphanumerical characters
    print (any(i.isalnum() for i in s))

    #alpha
    print( any(i.isalpha() for i in s))

    #numerical
    print( any(i.isdigit() for i in s))

    #lowercase
    print( any (i.islower() for i in s))

    #uppercase
    print ( any(i.isupper() for i in s))

#Note we need (any x for i in s)

Task 2

def wrap(string, max_width):
    return(“\n”.join([string[i:i+max_width] 
    for i in range(0, len(string), max_width)]))
