7.4 Practice



Continuously ask a user to enter words. (Make sure that the input given is actually just 1 word.) Store the words in a list. Stop asking the user for words if they enter an empty string (the string has no characters or is completely whitespace). Convert all of the words in the list into uppercase. Print the resulting list. (If the user quits right away, print an empty list.)


Create a program that takes a string from the user and prints the number of vowels that are in the string.


Write a Python program to add "ing" at the end of a given string (length of the string should be at least 3).
If the given string already ends with "ing", add "ly" instead
If the string length of the given string is less than 3, leave it unchanged.
Print the resulting string
Note: adapted from W3Resource, problem 6


Write a Python program to print a string from a given string where all occurrences of its first char have been changed to "$" except the first char itself.
Sample String: 'restart'
Expected Result: 'resta$t'
