Just setting up my twttr

When texting or tweeting, it’s not uncommon to shorten words to save time or space, as by omitting vowels, much like Twitter was originally called twttr. In a file called twttr.py, implement a program that prompts the user for a str of text and then outputs that same text but with all vowels (A, E, I, O, and U) omitted, whether inputted in uppercase or lowercase.

  • Recall that a str comes with quite a few methods, per docs.python.org/3/library/stdtypes.html#string-methods.
  • Much like a list, a str is “iterable,” which means you can iterate over each of its characters in a loop. For instance, if s is a str, you could print each of its characters, one at a time, with code like:
    for c in s:
        print(c, end="")


Before You Begin

Log into cs50.dev, click on your terminal window, and execute cd by itself. You should find that your terminal window’s prompt resembles the below:


Next execute

mkdir twttr

to make a folder called twttr in your codespace.

Then execute

cd twttr

to change directories into that folder. You should now see your terminal prompt as twttr/ $. You can now execute

code twttr.py

to make a file called twttr.py where you’ll write your program.

How to Test

Here’s how to test your code manually:

  • Run your program with python twttr.py. Type Twitter and press Enter. Your program should output:
  • Run your program with python twttr.py. Type What's your name? and press Enter. Your program should output:
    Wht's yr nm?
  • Run your program with python twttr.py. Type CS50 and press Enter. Your program should output

You can execute the below to check your code using check50, a program that CS50 will use to test your code when you submit. But be sure to test it yourself as well!

Green smilies mean your program has passed a test! Red frownies will indicate your program output something unexpected. Visit the URL that check50 outputs to see the input check50 handed to your program, what output it expected, and what output your program actually gave.

How to Submit

In your terminal, execute the below to submit your work.
