How to properly concatenate string literal to string variable and reassign to variable

Question

I'm trying to concatenate a string literal to a string variable and reassign this value to the same variable.

I've tried the += operator and something like

string = string + "another string"

but that doesn't work.

Here is my code.

userWord = input("Enter a word: ").upper()

# Prompt the user to enter a word and assign it to the userWord variable


for letter in userWord:
    # Loops through userWord and concatenates consonants to wordWithoutVowels and skips vowels
    if letter == "A" or letter == "E" or letter == "I" or letter == "O" or letter == "U":
        continue
    wordWithoutVowels += userWord # NameError: name "wordWithoutVowels" is not defined

print(wordWithoutVowels)

Answer 1

Firstly, I think you intended to do wordWithoutVowels += letter, not the entire userWord. Secondly, that expression is the same as wordWithoutVowels = wordWithoutVowels + userWord, which means that wordWithoutVowels needs to be defined before it.

Simply add the following before the for loop

wordWithoutVowels = ''

---

Edit:

As @DeveshKumarSingh mentioned, you can further improve the loop by using the following if condition instead of using continue

if letter not in ['A','E','I','O','U']:
    wordWithoutVowels += letter
