Python 试图打开文件时出现名称错误
我用Python做了一个测验,并尝试将测验分数和用户名一起保存在一个.txt文件中,但我一直收到一条错误消息,我似乎不知道为什么 这是我的代码:Python 试图打开文件时出现名称错误,python,file,syntax-error,Python,File,Syntax Error,我用Python做了一个测验,并尝试将测验分数和用户名一起保存在一个.txt文件中,但我一直收到一条错误消息,我似乎不知道为什么 这是我的代码: import random import json score = 0 turn = 1 turn = turn + 1 name = raw_input("what is your name?") num_class = input("What class are you in?

运行时,我不断收到此错误消息:
Traceback (most recent call last):
第47行,在
string=file.read()
IOError:文件未打开以进行读取
有人能帮我一下吗?问题是你没有定义
文件;您定义了文件名
。您只需将该行更改为open(file\u name,“r”)
file\u n
应该是file\u name
我假设?行file=open(file\u n,“r”)
应该是file=open(file\u name,“r”)
创建文件需要更改什么@Yaroslav Admin@James Tobini注意到了这一点,并对其进行了更改,但我仍然收到一条错误消息string=file.read()IOError:file not open for readingi我意识到以前但现在我收到了这条错误消息Traceback(最近一次调用最后一次):string=file.read()IOError:文件未打开以供读取。您一定遗漏了其他内容。你能看到我可能错过的东西吗
