在vim中，我想编写以下代码：
def a():
if a: pass
elif b: pass
else: pass
我使用自动缩进，但代码将缩进为：
def a():
if a: pass
elif b: pass
else: pass
else语句的自动缩进错误。我该怎么解决这个问题？
请注意，以下代码片段正确缩进：
def a():
if a: pass
else: pass

我认为这是Vim版本中包含的indent/python.vim文件中的一个错误。
要检查它，请将文件从$VIMRUNTIME/indent/python.py复制到您的home-vim目录（例如$HOME/.vim/indent/python.py）中，并查找以下段落（靠近文件末尾）：
" Unless the previous line was a one-liner
if getline(plnumstart) =~ '^s*(for|if|try)>'
return plindent
endif
更改条件以检查关键字elif也是：
" Unless the previous line was a one-liner
if getline(plnumstart) =~ '^s*(for|if|elif|try)>'
return plindent
endif
重新启动Vim并完成！
Vim之所以这么做，是因为您的代码不是惯用的，因此它做出了正确的假设。问题在于将pass（或任何其他表达式）放在同一行。如果你把它们放在新的线路上，这是不会发生的。事实上，vim可能期望（或隐含地试图鼓励）PEP-008，它是Python的风格指南。我在那里链接的部分（接近结尾）确切地谈到了你所面临的问题，但没有谈到如何让vim屈从于你的意愿。
我假设您不关心编写地道的Python，并回答您的问题：
在安装vim的不可执行文件的目录中，您会发现一个名为indent的目录，在该目录中您会找到一个称为python.vim的文件。
在第168行，您将看到默认情况下它会自动为您删除该行。只有当前一行是以if、for或try语句开头的"一行"时，它才不会执行此操作。
你可以自己制作，也可以向vim提交修复程序，但在此期间没有可供使用的设置。一个"修复"是复制文件并应用您的更改，然后告诉vim使用它。
