令牌错误：多行语句中的EOF

Question

下面的代码让我遇到了这个错误：“Token Error: EOF in multi-line statement”。这个错误是什么意思？我该怎么解决它？

import easygui
import time
namegui = easygui.enterbox(msg='Enter your name:', title='Name query', default='Gian')
situationgui = easygui.enterbox(msg='Please enter your situation:', title='Thought Log(Situation)')

thinking_trapsgui = easygui.enterbox(msg='Please identify your thinking traps: \n \n'

alt_behaviorgui = easygui.enterbox(msg='Please enter alternative behavior:', title='Thought Log(Alt Behavior)')
alt_thoughtsgui = easygui.enterbox(msg='Please enter alternative thoughts:', title='Thought Log(Alt Thoughts)')
yeargui = easygui.enterbox(msg='Enter the current year:', title='Current Year', default='2011')

am_pmgui = easygui.enterbox(msg='Please enter either am or pm:', title='AM OR PM')
file = open('Thought Record 1.0.txt', 'a')
file.write(namegui + '\n')
file.write(daygui)
file.write('/')
file.write(monthgui)
file.write('/')
file.write(yeargui)
file.write('\n')
file.write('Your situation:')
file.write(situationgui)
file.write('\n')
file.write('Your thoughts:')
file.write(thoughtsgui)
file.write('\n')
file.write('Your emotions:')
file.write(emotionsgui)
file.write('\n')
file.write('Your behavior:')
file.write(behaviorgui)
file.write('\n')
file.write('Thinking traps:')
file.write(thinking_trapsgui)
file.write('\n')
file.write('Alternative bahvior:')
file.write(alt_behaviorgui)
file.write('\n')
file.write('Alternative thoughts:')
file.write(alt_thoughtsgui)
file.write('\n')
file.write('\n')
file.close()

这个错误是在我添加了以下几行代码之后才出现的。

BAI_var = easygui.choicebox(
    msg='Please identify your thinking traps: \n \n',
    title='Thought Log(Identify Your Thinking Traps)',
    choices=('FORTUNE-TELLING: This occurs when we predict that things will turn out badly. However, we cannot predict the future because we do not have a magic ball! \n \n
             'MIND-READING: This happens when we believe that we know what others are thinking and we assume that they are thinking the worst of us. However, we cannot mind-read so we do not know what others are thinking! \n \n'
             'LABELING: Sometimes we talk to ourselves in a mean way and we use a single negative word to describe ourselves. However, this kind of thinking is unfair and we are too complex to be summed up in a single word! \n \n'
             'FILTERING: This happens when we take note of all the bad things that happen, but ignore any good things. \n \n'
             'OVERESTIMATING: This happens when we believe that something that is unlikely to occur is actually about to happen. \n \n'
             'CATASTROPHIZING: This is when we imagine the worst possible thing is about to happen and we will be unable to cope with it. \n \n'
             'OVERGENERALIZING: This is when we use words like always or never to describe situations or events. This is a problematic way of thinking because it does not take all situation or events into account \n \n')

我在Mac OS X 10.6上运行的是Python 2.5。

Answer 1

你在占卜那一行缺少了结束的引号。

这个问题很容易找到，因为在那一行的语法高亮显示会变得不同。

Answer 2

这不是直接回答原问题，但因为我在网上搜索时找到了这里，所以想分享一下我的经历。我遇到这个错误是因为一个多余的括号！不过这个错误是来自于 flake8 工具。下面是一个可以重现这个错误的代码片段：

import socket


def all_good(name):
    name_line = f"Name: {name}")
    print(name_line)

我把这个代码保存到了一个叫 error.py 的文件里。现在如果我用 flake8 来检查它：

$ flake8 error.py 
error.py:1:1: E902 TokenError: EOF in multi-line statement

这让我很困惑，因为代码里根本没有多行语句！最后我找到了问题，但这个故事的教训是，如果我先用 Python 解释器运行一下，可能会更快找到错误：

$ python3 error.py 
  File "error.py", line 5
    name_line = f"Name: {name}")
                               ^
SyntaxError: unmatched ')'

修复它：

import socket


def all_good(name):
    name_line = f"Name: {name}"
    print(name_line)

现在 flake8 就能正常工作了：

$ flake8 error.py 
error.py:1:1: F401 'socket' imported but unused

这很明显，但记住：先用 python3 检查代码，然后再用代码检查工具或其他检查器。

Answer 3

你在choices变量的第一行末尾没有加上撇号（'）。
