How to correct python indentation using vim?

Ref: https://iqbalnaved.wordpress.com/2013/12/09/vim-tip-how-to-fix-python-exception-indentationerror/

The problem is usually with mixup in tabs and spaces –

Solution 1

1. Apply following command in Vim to highlight tabs, spaces and other whitespace differently.

1	:set listchars=tab:>-,trail:-,eol:$ list

2. Apply the following to set correct width

1	:set shiftwidth=4 tabstop=4 expandtab

3. running

1

:retab

to fix the problem,Vim automatically fixes all indentation space and tab mix ups.

Solution 2

1. set ‘list’, so that you can see the whitespace and change.

Have the following mapping in .vimrc for this:

nnoremap    <F2> :<C-U>setlocal lcs=tab:>-,trail:-,eol:$ list! list? <CR>

2. Ensure ‘expandtab’ is reset, check using following command –

:verbose set ts? et?

3. To expand all leading spaces (wider than ‘tabstop’), use retab.

retab takes a range, so specify % to mean “the whole file”.

:set tabstop=4      " To match the python file

:set noexpandtab    " Use tabs, not spaces

:%retab!            " Retabulate the whole file
