Python在我的MacVim上意外縮進

Question

我試圖將下面的python代碼複製粘貼到我的macvim中，並且出現「Unexpected indent」。

## Can build up a dict by starting with the the empty dict {} 
## and storing key/value pairs into the dict like this: 
## dict[key] = value-for-that-key 
dict = {} 
dict['a'] = 'alpha' 
dict['g'] = 'gamma' 
dict['o'] = 'omega' 

print dict ## {'a': 'alpha', 'o': 'omega', 'g': 'gamma'} 

print dict['a']  ## Simple lookup, returns 'alpha' 
dict['a'] = 6  ## Put new key/value into dict 
'a' in dict   ## True 
## print dict['z']     ## Throws KeyError 
if 'z' in dict: print dict['z']  ## Avoid KeyError 
print dict.get('z') ## None (instead of KeyError) 

我檢查是否因爲混合了製表符和空格，但什麼也沒找到;

python -tt new.py 
File "new.py", line 4 
dict = {} 
^ 
IndentationError: unexpected indent 

還發現，可能是因爲自動縮進通過我的Vim的，並試圖通過使用

:set paste 

這也不起作用禁用它。下面是我的.vimrc文件

set nobackup 
set nowritebackup 
set noswapfile 
set lines=40 
set columns=80 
set tabstop=4 
set shiftwidth=4 
set softtabstop=4 
set autoindent 
set smarttab 
set retab 
set paste 
filetype indent on 
filetype on 
filetype plugin on 

這是文件

我被愚蠢的和失去了一些東西很簡單的hexdump都可以？你會推薦我進入基於Python的IDE如PyCharm嗎？

Answer 1

在你的hexdump中，在第一行代碼之前有兩個空格。這意味着您的初始縮進是兩個空格，python完全不需要空格（或製表符）。字節0x9e和0x9f是空格，字節0xa0是dict = {}中的'd'。

如果選項'hlsearch'打開，您可以看到/^\s*的起始空白。
