are you trying to format the file with the proper indentations?

Google for polystyle.

It's a tool that reformats a program (in several languages) using an
example you must provide (let's call it a "style sheet", written in
Python or whatever) of how you would want to format it.

You can then reformat any python program according to your "style sheet"

Is what possible? What do you want the tool to do?

sometimes i need to merge some code snippets from files into a file,
and when time comes to do this merge, i always find it difficult to
reformat the python code
because after pasting and copy, the code indentation different from
one to another.
and it is the tedious job for us to manually move the code from one
segment to another.

so i would like to have a tool to intelligently format the code for me
and make the code more beautiful
and automated.

This is not possible. Consider the following situation:


code a:


if something:
do_something()


code b:

if anything:
do_something_else()


No lets say you copy b after a. At which level should it be? Like this


if something:
do_something()

if anything:
do_something_else()


Or like this?

if something:
do_something()

if anything:
do_something_else()



Both are semantically radically different, and only you know which one
is the right one.

What my editor (emacs) allows, and other IDEs/editors as well is to mark
blocks, and shift these wholesome left or right, to get the desired
indention level.

The only thing that migh be automatized after a piece of code is valid
is normalization, like de-tabifying or making everything based on 4
space characters indention. No idea if there is something out there that
does that.

In vim, you can do something like:

:set tabstop=4
:set expandtab
:retab

I have to agree with Diez, there is no way to automate this. Some
human intervention is needed. What I would like is an editor that will
indicate what Python will consider a logical block (and sub-block, and
sub-sub-block, etc.)
It's complicated. I've tried to think of a way to do it, and have
gotten lost after a few changes of indentation.
Does anyone know of such a thing?
I miss curly braces with an editor that will highlight matching
parentheses, braces, etc.

At least with Windows, you get a number of scripts included in your
Python install - under the python directory/tools/scripts. There are
several scripts here which are intended to help with indentation
issues - such as reindent and pindent. Those might help you out some.

Nonetheless, it would be better to implement coding standards that
everyone can stick to.

Agreed. You can't solve social issues with program.
