I m getting an IndentationError (or a TabError). How do I fix it? (6 answers)

Closed last month.

我正在制作一个“灰色”节目,如果我的服务器上台的话,会对其进行检查。如果是 t,它会tw倒。之后,它会回头来。

但是,当我执行我的法典时,我发现这一错误:

  File "Tweet_bot.py", line 31
    textfile = open( /root/Documents/server_check.txt , w )
    ^
IndentationError: unexpected indent

我的分节守则如下:

try :
    response = urlopen( url )
except HTTPError, e:
    tweet_text = "Raspberry Pi server is DOWN!"
    textfile = open( /root/Documents/server_check.txt , w )
    textfile.write("down")
    textfile.close()

except URLError, e:
    tweet_text = "Raspberry Pi server is DOWN!"
    textfile = open( /root/Documents/server_check.txt , w )
    textfile.write("down")
    textfile.close()
else :
    html = response.read()
    if textfile = "down":
        tweet_text = "Raspberry Pi server is UP!"
        textfile = open( /root/Documents/server_check.txt , w )
        textfile.write("up")
        textfile.close()
    if textfile = "up":
        tweet_text = ""
        pass
if len(tweet_text) <= 140 and tweet_text > 0:
    api.update_status(status=tweet_text)
else:
    pass

Answer 1

你们正在混合制片和空间:

>>> from pprint import pprint
>>> pprint(   
...     tweet_text = "Raspberry Pi server is DOWN!"
...         textfile = open( /root/Documents/server_check.txt , w )
...    .splitlines())
[  ,
      tweet_text = "Raspberry Pi server is DOWN!" ,
 "	textfile = open( /root/Documents/server_check.txt , w )"]

注:在第二行开始时,但第一个有4个空间。

灰 Python将tab片扩大到第8栏,该栏比第1行的4个空间多。因此,第二行被压缩到2<>2>>>>> 降级水平,而第一级则只降级。

甲型六氯环己烷(PEP 8)建议使用only/em>的空间:

Spaces are the preferred indentation method.

and

装有制片和空地混合物的 Python2代码应完全改用空间。

as getting your tabs configured correctly and not accidentally muck up indentation by mixing in a few spaces is hard.

请您的编辑在您的编辑时将表格转换成空间;这样,你才能使用TAB的关键板块,而不落入这一陷阱。
