Write a program to compare two strings. One of the strings should be already stored in your program as password. Now take user input for a guess and compare this input with the pre stored password. If both of them match then print "Valid password" otherwise print "Sorry! Wrong password".

Design a program with an algorithm that will take a string from the user and then decide if each character in that string is unique. For example, if you ask the user to enter a string and that user enters the world ‘hello’, the result of the algorithm implementedshould return ‘false’ or ‘not unique’. If the user enters a string such as the word ‘phone’ the program will return ‘true’ or ‘unique’ since every character in the word phone is unique and is not repeated. An example of this program follows: Output should show as :  enter a string rizma This string has all the unique characters  would u like to continue?(y for yes n for no) y Enter a string waali This string is not unique     Your code should work for all strings and essentially all characters, as many examples will be tested.

Write a program that receives an integer from the user and prints Large if that number is greater than or equal to 100, prints average if that number is between 20 and 100, and prints Small if that number is less than or equal to 20. You can get an input from user and convert it to an integer using a = int(input('Please enter an integer:'))

Implement a program that requests four numbers from the user. Your program should compute the average of the first three numbers and compare the average to the fourth number. If they are equal, your program should print True
