        # get next block
        category, question, answers, correct, score, explanation = next_block(trivia_file)

    trivia_file.close()
    pic_save(name, final_score)
    print("That was the last question!")
    print("You're final score is", final_score)
    pic_read()

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

最佳答案

可能要执行的操作是将welcome的返回值分配给名为name的变量，否则返回值将丢失。

name = welcome(title)
