CS50P PSET2: Setting up my twttr: How to union two string

Question

vowel = ["A", "E", "I", "O", "U", "a", "e", "i", "o", "u"]

vowel_remove = input("Input: ")
print("Output: ", end="")

for vowels in vowel:
    lower_vowel = vowels.lower()
    # print(lower_vowel)
    if vowels in vowel_remove:
        print(vowel_remove.replace(vowels, ""))

print()

Input: Apple

Output: Appl
pple

I get two output with each one of the vowel is removed one by one and making two output.

Is there a way to union the different string like seeing the similarity of the characters and removing the odd one like for example

Appl and pple the similar ones are ppl and the odd one from each of them are A and e

is it possible to union ppl

Answer 1

The below code iterates the input and removes the vowels and save the non vowels to an output variable.

vowel = ["A", "E", "I", "O", "U", "a", "e", "i", "o", "u"]
vowel_remove = input("Input: ")
print("Output: ", end="")

output = ""
for char in vowel_remove:
    if char in vowel:
        continue
    else:
        output += char
print(output)

output

Input: Apple
Output: ppl

To find unique characters in 2 strings you can use

print(''.join(set('Appl').intersection('pple')))

But this will remove repeating characters for example, 'p' in the above case.

output
