我正在尝试制作一个数学游戏，我想实现一个高分跟踪器，它将人的高分以及他们的名字保存在文本文件中，并且它为每个玩家做到了这一点。如果玩家再次玩，则可以从文本文件中调出他的高分。到目前为止，这是我的代码：
import random
def game():
while 1:
c1 = input("Would you like to play from the beginning?").lower()
if c1 == "yes":
lvl1()
elif c1 == "no":
print("Your score was:", score)
main()
break
else:
game()
quit()
def lvl1():
print("LEVEL 1")
global score
score = 0
operators = ("+","-")
while 1:
No1 = random.randint(1,10)
No2 = random.randint(1,10)
Op = random.choice(operators)
if Op == "+":
A1 = No1 + No2
print("What is", No1, Op, No2,"?")
answer = float(input("Enter your answer"))
elif Op == "-":
A1 = No1 - No2
print("What is", No1,Op,No2,"?")
answer = float(input("Enter your answer"))
if answer == A1:
print("Correct!")
score = score + 1
print(score)
else:
print("Incorrect! Try again...")
game()
if score == 5:
break
print("Congratulations on making it to level 2!")
lvl2()
def lvl2():
print("LEVEL 2")
global score
score = 5
operators = ("+","-","x")
while 1:
No1 = random.randint(1,15)
No2 = random.randint(1,15)
Op = random.choice(operators)
if Op == "+":
A1 = No1 + No2
print("What is", No1, Op, No2,"?")
answer = float(input("Enter your answer"))
elif Op == "-":
A1 = No1 - No2
print("What is", No1,Op,No2,"?")
answer = float(input("Enter your answer"))
else:
A1 = No1 * No2
print("What is", No1,Op,No2,"?")
answer = float(input("Enter your answer"))
if answer == A1:
print("Correct!")
score = score + 1
print(score)
else:
print("Incorrect! Try again...")
game()
if score == 10:
break
print("Congratulations on making it to level 3!")
lvl3()
def lvl3():
print("LEVEL 3")
global score
score = 10
operators = ("+","-","x")
while 1:
No1 = random.randint(10,50)
No2 = random.randint(10,50)
Op = random.choice(operators)
if Op == "+":
A1 = No1 + No2
print("What is", No1, Op, No2,"?")
answer = float(input("Enter your answer"))
elif Op == "-":
A1 = No1 - No2
print("What is", No1,Op,No2,"?")
answer = float(input("Enter your answer"))
else:
A1 = No1 * No2
print("What is", No1,Op,No2,"?")
answer = float(input("Enter your answer"))
if answer == A1:
print("Correct!")
score = score + 1
print(score)
else:
print("Incorrect! Try again...")
game()
if score == 15:
break
print("Congratulations on making it to level 4!")
lvl4()
def lvl4():
print("LEVEL 4")
global score
score = 15
operators = ("+","-","x")
while 1:
No1 = random.randint(10,100)
No2 = random.randint(10,100)
Op = random.choice(operators)
if Op == "+":
A1 = No1 + No2
print("What is", No1, Op, No2,"?")
answer = float(input("Enter your answer"))
elif Op == "-":
A1 = No1 - No2
print("What is", No1,Op,No2,"?")
answer = float(input("Enter your answer"))
else:
A1 = No1 * No2
print("What is", No1,Op,No2,"?")
answer = float(input("Enter your answer"))
if answer == A1:
print("Correct!")
score = score + 1
print(score)
else:
print("Incorrect! Try again...")
game()
if score == 20:
break
print("Congratulations! You have completed the game.")
main()
def gethighscore():
# Default high score
highscore = 0
# Try to read the high score from a file
try:
highscorefile = open("highscore.txt", "r")
name = str(highscorefile.read())
highscore = int(highscorefile.read())
highscorefile.close()
print("The high score is", highscore)
except IOError:
# Error reading file, no high score
print("There is no high score yet.")
return highscore
def savehighscore(new_high_score):
try:
# Write the file to disk
highscorefile = open("highscore.txt", "w")
L = [name, new_high_score]
highscorefile.write(str(L))
highscorefile.close()
except IOError:
# Hm, can't write it.
print("Unable to save the high score.")
def main():
# Get the high score
highscore = gethighscore()
if score < highscore:
print("Yea! New high score!")
savehighscore(score)
else:
print("Better luck next time.")
print("Welcome to the maths game.")
name = input("What is your name?")
print("IT'S TIME!")
lvl1()
quit()
我目前收到此错误：
Your score was: 2
Traceback (most recent call last):

ValueError: invalid literal for int() with base 10: ''
答案 0 :(得分：1)
列表不能直接写入文件，而是在以下行中：
highscorefile.write(str(L))
它被转换为字符串。当您在gethighscore()中阅读文件时，结果也是字符串，不是列表。
您可以通过多种方式保存和阅读高分。让我告诉你一个非常简单的方法：
名为ast的第一个导入模块。然后更改您的gethighscore()
def gethighscore():
# Default high score
highscore = 0
# Try to read the high score from a file
try:
highscorefile = open("highscore.txt", "r")
fileContent = highscorefile.read()
highscorefile.close()
# This converts a string list to list
L = ast.literal_eval(fileContent)
name = L[0]
highscore = L[1]
print("The high score is", highscore)
except IOError:
# Error reading file, no high score
print("There is no high score yet.")
return highscore
希望它有所帮助！如果您仍然有任何问题请注释。
