Lab 4.01 - de_vowel

Remove the Vowels

Create a function, de_vowel, which will take a string as input and return a copy of that string with all the vowels removed. Otherwise, the string should be the same.

  1. Create the function contract for de_vowel.
  2. Write de_vowel using a for loop
  3. Provide a few examples that confirm de_vowel works as expected:
    • What if the string is all vowels?
    • What if there are no vowels?
    • What if there is a mix of vowels and non-vowels and spaces?

Example

Example of the file: 

# contract goes here
def de_vowel(a_string): 
    # your code goes here
no_vowels = de_vowel("This sentence has no vowels")
print(no_vowels)
# examples go here

Example running of the code: 

>>> python3 de_vowel_lab.py
Ths sntnc hs n vwls

Bonus!

Use a counter (variable you define outside of a loop to keep track of a value inside a loop) to create a function count_vowels.

count_vowels takes in a string and returns an int representing the number of vowels in the string.
