Question

Python Programming Assignment:

Write a function to take a string S that returns True if the letters are in ascending order and False otherwise. To do this go over each letter and check that it is less than the letter that precedes it.

Then write a function main that gets one input from the user, then if passing that input to the function above returns True, then show "String is in order", otherwise show " String is unordered".

Answer 1

def isSorted(lst):
    for i in range(len(lst)):
        for j in range(i+1, len(lst)):
            if(lst[i] > lst[j]):
                return False
    return True

def main():
    s = input("Enter string: ")
    res = isSorted(s)
    if(res):
        print("String is in order")
    else:
        print("String is unordered")

main()
