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)]))
