Usage
~~~~~

Description
-----------

Life is short, format the code automatically

(人生苦短，自动排版)

Tidy python scripts

Effect
------

Convert Tabs to Spaces(Tabs sized can be decide in argument -t, default
is 4)

Delete white spaces at end of line

Own thoughts about code format, some part are different from PEP8
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

PEP8: `Whitespace in Expressions and
Statements <https://www.python.org/dev/peps/pep-0008/#id23>`__ Not
compliant

Always add 1 white space between operators

Align dict and assignment statments like following

From:
~~~~~

.. code:: python

    list = [1, 2, {
       'Alicedefg': '2341',
       'Beth' : "c",
       'Cecil' : '3258',
    }, 4]

                    'Cecil'     : '3258',
                    }, 4]

VIM Integration
---------------

Below example binds the tidy fucntion to F7

.. code:: vim

    command -range=% -nargs=* TidyPython <line1>,<line2>!python -m pythontidy2
    fun DoTidyPython()
        let Pos = line2byte( line( "." ) )
        :TidyPython
        exe "goto " . Pos
    endfun
    au Filetype python nmap <F7> :call DoTidyPython()<CR>
    au Filetype python imap <F7> <ESC>:call DoTidyPython()<CR>
    au Filetype python vmap <F7> :TidyPython<CR>
