Indentation Error in Python
提问by sharkbait
I can't compile because of this part in my code:
由于我的代码中的这一部分，我无法编译：
if command == 'HOWMANY':
opcodegroupr = "A0"
opcoder = "85"
elif command == 'IDENTIFY':
opcodegroupr = "A0"
opcoder = "81"
I have this error:
我有这个错误：
Sorry: IndentationError: ('unindent does not match any outer indentation level', ('wsn.py', 1016, 30, "\t\telif command == 'IDENTIFY':\n"))
抱歉: IndentationError: ('unindent 不匹配任何外部缩进级别', ('wsn.py', 1016, 30, "\t\telif command == 'IDENTIFY':\n"))
But I don't see any indentation error. What can be the problem?
但我没有看到任何缩进错误。可能是什么问题？

In doubt change your editor to make tabs and spaces visible. It is also a very good idea to have the editor resolve all tabs to 4 spaces.
有疑问，请更改您的编辑器以使选项卡和空格可见。让编辑器将所有制表符解析为 4 个空格也是一个很好的主意。

You are mixing tabs and spaces.
您正在混合制表符和空格。
Find the exact location with:
使用以下命令查找确切位置：
python -tt yourscript.py
and replace alltabs with spaces. You really want to configure your text editor to only insert spaces for tabs as well.
并更换所有用空格选项卡。您确实希望将文本编辑器配置为仅为制表符插入空格。

Did you maybe use some <tab>instead of spaces?
你可能使用了一些<tab>而不是空格吗？
Try remove all the spaces before the code and readd them using <space>characters, just to be sure it's not a <tab>.
尝试删除代码前的所有空格并使用<space>字符读取它们，以确保它不是<tab>.

In Notepad++
在记事本++中
View --->Show Symbols --->Show White Spaces and Tabs(select)
查看 ---> 显示符号 ---> 显示空格和制表符（选择）
replace all tabs with spaces.
用空格替换所有制表符。

For Sublime Text Editor
对于 Sublime 文本编辑器
Indentation Error generally occurs when the code contains a mix of both tabs and spaces for indentation. I have got a very nice solution to correct it, just open your code in a sublime text editor and find 'Tab Size' in the bottom right corner of Sublime Text Editor and click it. Now select either
当代码包含用于缩进的制表符和空格的混合时，通常会发生缩进错误。我有一个非常好的解决方案来纠正它，只需在 sublime 文本编辑器中打开您的代码，然后在 sublime 文本编辑器的右下角找到“标签大小”并单击它。现在选择
'Convert Indentation to Spaces'
OR
或者
'Convert Indentation to Tabs'
Your code will work in either case.
您的代码在任何一种情况下都可以使用。

It happened to me also, but I got the problem solved. I was using an indentation of 5 spaces, but when I pressed tab, it used to put a four space indent. So I think you should just use one thing; i.e. either tab button to add indent or spaces. And an ideal indentation is one of 4 spaces. I found IntelliJ to be very useful for these sort of things.
这也发生在我身上，但我解决了问题。我使用了 5 个空格的缩进，但是当我按下 Tab 键时，它曾经放置了一个 4 个空格的缩进。所以我认为你应该只使用一件事；即要么选项卡按钮添加缩进或空格。理想的缩进是 4 个空格之一。我发现 IntelliJ 对这类事情非常有用。

This has happened with me too, python is space sensitive,
so after " :"(colon)
you might have left a space,
for example:
[space is represented by "."]
这也发生在我身上，python 对空间敏感，所以在“ :”（冒号）之后你可能会留下一个空格，
例如：[空格由“ .”表示]
`if command == 'HOWMANY':.
opcodegroupr = "A0"
opcoder = "85"
elif command == 'IDENTIFY':.
opcodegroupr = "A0"
opcoder = "81"`
so try removing the unnecessary spaces,if you open it in IDE your cursor will be displayed away from ":" something like :- "if command == 'HOWMANY': |"
....whereas it should be:- "if command == 'HOWMANY':|"
所以尝试删除不必要的空格，如果你在 IDE 中打开它，你的光标将显示在远离 ":" 的地方，类似于 :- " if command == 'HOWMANY': |"
.... 而它应该是：- " if命令 == 'HOWMANY':|"
