Dieses Python-Quiz macht mich verrückt

Question

Ich bin neu in StackOverflow (1. Zeit Posting) und neu in der Programmierung mit Python. Derzeit in einem Kurs über Udacity eingeschrieben. Ich habe eine sehr schwere Zeit mit einem Projekt, das wir für diesen Kurs erhalten haben und beschlossen, hierher zu kommen, um zu sehen, ob jemand helfen könnte.

Das Projekt soll ein Quiz mit 4 Leerzeichen erstellen, die vom Spieler korrekt beantwortet werden müssen. Es ist erforderlich, dass das Quiz mit der richtigen Antwort ausgedruckt wird, aber es fällt mir sehr schwer, das richtig auszudrucken.

Mein Code ist unten. Ich würde mich über jede Hilfe oder Ratschläge freuen, die ich dazu bekommen kann.

Danke!

Answer 1

Hier ist eine Arbeitsversion Ihres play_game() -Methode:

def play_game(quiz, parts_of_speech): 
    replaced = [] 
    i = 0 
    quiz = quiz.split() 
    for word in quiz: 
     replacement = word_in_pos(word, parts_of_speech) 
     if replacement is not None: 
      user_input = raw_input("Type an answer for: " + replacement + " ") 
      guesses = 0 
      while user_input != answers[i]: 
       guesses = guesses + 1 
       if guesses == 5: 
        return "\nGame Over! Better luck next time. \n" 
       print "Incorrect, try again \n" + " ".join(replaced) + " " + replacement 
       user_input = raw_input("Type an answer for: " + replacement + " ") 
      replaced.append(user_input) 
      print "Correct \n" + " ".join(replaced) 
      i = i + 1 
     else: 
      replaced.append(word) 
    replaced = " ".join(replaced) 
    return replaced 

Die wichtigste Änderung ist die replaced Liste zu verzögern, zu modifizieren, bis die richtige Antwort gegeben wurde. Das vereinfacht einen Großteil des Codes und macht die word Variable überflüssig.
