我正在尝试运行一个程序来管理基于文本文件内容的测验 . 我的代码看起来像这样：

该计划管理美国州，首都和州长的测验

全球有多少问题

HOW_MANY_QUESTIONS = 10

打开文件并附上答案

answers_file =开放（ 'quiz_answers.txt'， 'R'）

打开文件以在结尾添加结果

results_file =开放（ 'quiz_results.txt'， 'W'）

def main（）：

#dictionary with quiz answers
answer_dictionary={}

#run create dictionary function, result is the answer dictionary
answer_dictionary=create_dictionary(answers_file)

#close the files
answers_file.close()
results_file.close()

go_again='yes'

while go_again=='yes':

    #get name
    name=input('Enter your name: ')

    #initialize count variable
    count=0

    #accumulator for number of correct answers
    number_correct=0

    for count in range(0,HOW_MANY_QUESTIONS+1):


        #pick question function
        answer=pick_question(answer_dictionary)

        if answer:

            number_correct+=1

    results_file.write(name,number_correct)



    go_again=input('Go again? ')

def create_dictionary（infile）：

#establish a dictionary 
dictionary={}

#initialize a key
key=0

#read the first line that is a state
state=infile.readline()

#strip the new line
state=state.rstrip('\n')

#while the line is not blank
while state!='':

    #add it as the dictionary key
    key=state

    #read the capital line
    capital=infile.readline()

    #strip new line
    capital=capital.rstrip('\n')

    #read the govenror line
    governor=infile.readline()

    governor=governor.rstrip('\n')

    #assign a list with capital and governor to the state key
    dictionary[key]=[capital,governor]

return dictionary

def pick_question（字典）：

#make a list containing the keys
keys=[]

#isolate the keys and append to the key list
for key in dictionary.keys():
    keys.append(key)

#import random
import random

#initialize an index for keys list
key_index=0

#randomly select the state to ask about
state_selection=random.randint(0,len(keys)-1)


key_index=state_selection

#assign value to capital and governor to randomly
#select which question to ask
capital=1
governor=2


#randomly select whether to ask for the governor or the capital
question_choice=random.randint(capital,governor)

#if the question choice is for capital
if question_choice==capital:

    #ask the capital question 
    question=input('What is the capital of',keys[key_index],'? ')

    #if the answer is a value for that key
    if question in keys[key_index]:

        #it is correct
        answer=True
#if the question choice is for governor
elif question_choice==governor:

    #ask the governor question
    question=input('Who is the governor of',keys[key_index],'?')

    #if the answer is a value for that key
    if question in keys[key_index]:

        #it is correct
        answer=True

return answer

主要（）

当我运行程序时，我得到的错误是：

state = infile.readline（）文件“/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/encodings/ascii.py”，第26行，解码返回codecs.ascii_decode（输入，self.errors） ）[0] UnicodeDecodeError：'ascii'编解码器无法解码位置36的字节0xff：序数不在范围内（128）

所以问题源于阅读文本文件的第一行;问题是什么？我该如何解决？我以前从未见过这个错误 . 提前致谢！
