似乎無法從函數返回值，第二個函數重新運行第一個函數

Question

我有一個瑣事程序，需要修改才能添加高分存儲功能。我修改了代碼的要求，但我得到一個錯誤：

line 99, in high_scores 
    entry = (score,name) 
NameError: name 'score' is not defined* 

我的問題是：在功能high_scores，我怎樣才能變score我在main()函數定義？我已經在主函數中返回了變量分數，但是我不知道如何在我的第二個函數high_scores()中使用它。

下面是代碼：

# Trivia Challenge 

# importing modules 
import sys, pickle 

def open_file(file_name, mode): 
    """Open a file, specify a file_name, and mode)""" 

    try: 
     the_file = open(file_name,mode) 
    except IOError as e: 
     print("Unable to open the file", file_name, "Ending program.\n", e) 
     input("\n\nPress the enter key to exit.") 
     sys.exit() 
    else: 
     return the_file 

def next_line(the_file): 
    """Return next line from the trivia file, formatted.""" 
    line = the_file.readline() 
    line = line.replace("/", "\n") 
    return line 

def next_block(the_file): 
    """Return the next block of data from the trivia file.""" 
    category = next_line(the_file) 
    question = next_line(the_file) 

    answers = [] 
    for i in range(4): 
     answers.append(next_line(the_file)) 
    correct = next_line(the_file) 
    if correct: 
     correct = correct[0] 

    explanation = next_line(the_file) 

    points = next_line(the_file) 
    if points: 
     points = int(points[0]) 

    return category, question, answers, correct, explanation, points 

def welcome(title): 
    """Welcome the player and get his/her name.""" 
    print("\t\tWelcome to Trivia Challenge!\n") 
    print("\t\t", title, "\n") 

def main(): 

    trivia_file = open_file("trivia.txt", "r") 
    titlea = next_line(trivia_file) 
    welcome(titlea) 
    score = 0 
    int(score) 

    # get first block 
    category, question, answers, correct, explanation, points = next_block(trivia_file) 
    while category: 
     # ask a question 
     print(category) 
     print(question) 
     print("Points for this question: ", points) 
     for i in range(4): 
      print("\t", i+1, "=", answers[i]) 
     answer = input("What's your answer?: ") 

     if answer == correct: 
      print("\nRight", end=" ") 
      score += points 
     else: 
      print("\nWrong.", end=" ") 
     print(explanation) 
     print("Score:", score, "\n\n") 

     # get next block 

     category,question,answers,correct,explanation,points = next_block(trivia_file) 

    trivia_file.close() 

    print("That was the last question!") 
    print("You're final score is", score) 

    if score > 0: 
     print("You have made the high scores list! Congratulations!)") 
     high_scores() 
    else: 
     print("You couldn't make the high scores list. Sorry") 
    return score # returning score so that i can call this function to use the variable in another function 

def high_scores(): 
    global name 
    try: 
     with open("high_scores.dat", "rb") as f: 
      scores = pickle.load(f) 
    except EOFError: 
     scores = [] 
    entry = (score,name) 

    scores.append(entry) 
    f = open("high_scores.dat", "wb") 
    pickle.dump(scores, f) 
    f.close() 
    print("Your achievement has been successfully saved to the high scores list")   

def display_scores(): 
    """display scores""" 
    try: 
     with open("high_scores.dat", "rb") as f: 
      scores = pickle.load(f) 
     print("\n\nName\t\tScore") 
     for entry in scores: 
      score, name = entry 
      print(name,"\t\t",score) 
    except EOFError: 
     print("Something unexpected occured...Ending the program") 
     input("\n\nPress the enter key to exit") 
     sys.exit() 


response = None 


while response != "1": 
    print(""" 
    1. Exit 
    2. Play the game 
    3. Display high scores 
""" 
    ) 
    response = input("Enter your choice: ") 
    if response == "2": 
     name = input("please enter ur name: ") 
     main() 
    elif response == "3": 
     display_scores() 

input("\n\nPress the enter key to exit.") 

Answer 1

它只是作爲參數傳遞：

def high_scores(score): 
    ... 

... 
def main(): 
    ... 
    high_scores(score)
