The Joy of Computing using Python

Week 8: Programming Assignment 1 - Palindrome

Due on 2021-09-23, 23:59 IST

Given a string as input, determine if it is a palindrome or not. (Ignore the spaces, case and any punctuation or special characters present in the string). 

Note: A palindromes is a string which has characters in the same order when read forward or backwards.

Input Format be like

First line of the input contains a string 

Output Format be like

Print 'Yes' if the given string is a palindrome, 'No' otherwise it is not palindrome

For Example the

Input is

Malayalam

And Output must be

Yes

if Input is

Python

and Output must be

No

--Solution--  

import re n=input() s = re.sub(r'[^\w\s]', '', n) s = s.replace(" ", "") s = s.lower() n = n.lower() n = re.sub(r'[^\w\s]', '', n) n = n.replace(" ", "") s=s[::-1] if n==s: print('Yes',end='') else: print('No',end='')

Week 8: Programming Assignment 2 - Anagrams

Due on 2021-09-23, 23:59 IST

Given two strings as input, determine if they are anagrams or not. (Ignore the spaces, case and any punctuation or special characters). 

Note: Anagrams are the strings which are made up of the same set of letters. For example : Mary and Army are anagrams.

Input Format be like

First line of the input contains the first string 

Second line of the input contains the second string

Output Format be like

Print 'Yes' if the given strings are anagrams, 'No' otherwise.

For Example the

Input is

Tom Marvolo Riddle

I am Lord Voldemort!!!

And Output must be

Yes

if Input is

Royal Challengers Bangalore

Rajasthan Royals

and Output must be

No

--Solution-- 

import re string = input() s = input() string = re.sub(r'[^\w\s]', '', string) s = re.sub(r'[^\w\s]', '', s) string = string.replace(" ", "") s = s.replace(" ", "") string = string.lower() s = s.lower() if (sorted(string) == sorted(s)): print("Yes",end="") else: print("No",end="")

Week 8: Programming Assignment 3 - Pangram

Due on 2021-09-23, 23:59 IST

Given an English sentence, check whether it is a pangram or not. A pangram is a sentence containing all 26 letters in the English alphabet

Input Format be like

A single line of the input contains a string

Output Format:

Print Yes or No

For Example the

Input is

The quick brown fox jumps over a lazy dog

And Output must be

Yes

if Input is

The world will be taken over by AI

and Output must be

No

--Solution--  

def ispangram(str): alphabet = "abcdefghijklmnopqrstuvwxyz" for char in alphabet: if char not in str.lower(): return False return True string = input() if(ispangram(string) == True): print("Yes",end='') else: print("No",end='')
