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.

Hints

  • 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

From the root of your repository execute cd 2-Loops So your current working directory is ...

	/2-Loops $:

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 /2-Loops/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:

  1. Run your program with python twttr.py. Type Twitter and press Enter. Your program should output:

     Twttr

  2. Run your program with python twttr.py. Type What's your name? and press Enter. Your program should output:

     Wht's yr nm?

  3. Run your program with python twttr.py. Type CS50 and press Enter. Your program should output:

     CS50

Commit your program to GITHUB

At the /2-Loops/twttr $ prompt in your terminal:

	git add -A

Add all changed files in the repository to be committed

	git commit -m “Upload completed twttr.py“

Commit all changes in the REPO with the comment “Upload completed twttr.py“ note: If the file is not complete, adjust the comment to describes what is being commited

	git push

Push all changes to the REPO
