Question

我有一个txt文件，如果我尝试打开它，python说：

runfile('/Users/costanzanaldi/Desktop/tesi/Tesi_Naldi/COdice _Python/untitled0.py', wdir='/Users/costanzanaldi/Desktop/tesi/Tesi_Naldi/COdice _Python')

Traceback (most recent call last):

  File "<ipython-input-30-b4bdfdd17ca2>", line 1, in <module>
    runfile('/Users/costanzanaldi/Desktop/tesi/Tesi_Naldi/COdice _Python/untitled0.py', wdir='/Users/costanzanaldi/Desktop/tesi/Tesi_Naldi/COdice _Python')

  File "/Users/costanzanaldi/anaconda/lib/python3.4/site-packages/spyderlib/widgets/externalshell/sitecustomize.py", line 685, in runfile
    execfile(filename, namespace)

  File "/Users/costanzanaldi/anaconda/lib/python3.4/site-packages/spyderlib/widgets/externalshell/sitecustomize.py", line 85, in execfile
    exec(compile(open(filename, 'rb').read(), filename, 'exec'), namespace)

  File "/Users/costanzanaldi/Desktop/tesi/Tesi_Naldi/COdice _Python/untitled0.py", line 13, in <module>
    in_file = open("POLO_SCIENTIFICO_(LAMMA).txt","r")

FileNotFoundError: [Errno 2] No such file or directory: 'POLO_SCIENTIFICO_(LAMMA).txt'

1）文件EXISTS！ 2）路径是正确的！它在桌面上！

Answer 1

您需要将目录更改为桌面才能访问该文件。您可以使用os模块执行此操作，如下所示：

import os
os.chdir("/path/to/Desktop")

Answer 2

据推测，这意味着该文件不在桌面上。（我假设您将Ethan＆＃34; / path / to / Desktop＆＃34;更改为系统中正确的路径，即＆＃34; / Users / costanzanaldi / Desktop＆＃34;？）。无论在哪里，你都需要给open（）提供POLO_SCIENTIFICO_（LAMMA）.txt的完整路径，除非你有chdir到正确的目录。我假设你在POLO_SCIENTIFICO_（LAMMA）.txt中得到了正确的字母大小写： - ）

文件txt：FileNotFoundError：[Errno 2]没有这样的文件或目录
