I have this line of code in a hangman program

word_list = [letter if letter in used_letters else '-' for letter in word]

and it takes the word that was picked and puts '-' in place of the letters that weren't guessed yet.

I just don't understand how the line works. How is there an if statement and a for loop inside a list? What is this if statement doing if letter in used_letters?

If someone could break it down for me I feel like it would make way more sense.

  • Have you tried rewriting the line into something else (such as many lines) to understand how it works? – OneCricketeer Oct 25 '22 at 19:56

True if True else False => True

True if False else False => False

If you take it apart, your cycle looks something like this:

word_list = []
for letter in word:
    if letter in used_letters:
        word_list.append(letter)
    else:
        word_list.append('-')
