python做图片美化软件,Python源代码美化

Hello, I did not find any reasonable pyhton source code beautifier

program (preferable gui).

Some would ask whyProgram it immediatly good.

(BTW: Would be a nice project, if I would have more spare time).

Ich have some foreign source, which are programed in a way

I don”t like, so I would like to have a tool, which automatically

processes following options:

Use Spaces, size: 4

convert structs like: if (a b): to if a b:

fill in spaces, but not in functions between operators:

a+=1 =a += 1

p(t + 1) =p(t+1)

convert:

self.scriptcount = self.scriptcount + 1 =self.scriptcount += 1

from “is” to “==” and “is not” to “!=” (ok a find replace could do that

easily also), but in a program that would be more comfortable.

break long lines (in a reasonable way)

make from:

if len(string) 0: =if string:

and

if if len(string)

detect mixed line ending

detect tabs mixed with space

trim trailing whitespaces.

…..

…..

Is there such a tool around/p>

Running Pylint or Pycheck automatically afterwards

would be the coronation. :)

That”s an unsafe conversion. I don”t think it is possible for a

reasonable program to determine statically that “is” is equivalent to

“==” except for trivial pieces of code.

Why, yes! Yes, there is:

o http://lacusveris.com/PythonTidy/PythonTidy.python

It doesn”t have a graphical user interface, and it doesn”t do

everything you want, and it isn”t reasonable (It”s of an unreasonable

size.), but it is a beginning.

For future reference, look in:

o http://cheeseshop.python.org/pypi

…. under “reformat.”

Well, most of the things you ask should be written as such, not written and

then beautified!

Use Spaces, size: 4

Your editor should support this.

convert structs like: if (a b): to if a b:

Well… that”s a matter of fact, not just style. Sometimes parentheses help

the reading; if a,b are not just plain names but somewhat complex

instructions, parentheses should stay.

fill in spaces, but not in functions between operators:

a+=1 =a += 1

p(t + 1) =p(t+1)

Code should be written this way.

self.scriptcount = self.scriptcount + 1 =self.scriptcount += 1

the += operator is syntactic sugar just to save time… if one doesn”t use

it I don”t think it”s a matter of beauty.

whatNo, I think you”re missing the difference between ”is” and ”==”. You

could say it the other way for None, True, False, e.g. if there”s a ”a ==

None” it could be safely converted to ”a is None”, but again: this should

be done while writing the code.

break long lines (in a reasonable way)

well… this could be useful sometimes, but again… ”reason” is usually

something human beings should employ, and shouldn”t be ”outsourced” to

computer programs.

make from:

if len(string) 0: =if string:

and

if if len(string)

That”s impossibile! Python is dynamically typed! How could the ”beautifier”

understand what the ”string” name is bound toIt could be whatever object!

detect mixed line ending

detect tabs mixed with space

trim trailing whitespaces.

Those are editor tasks.

Get a good Editor or IDE. You haven”t told us what OS are you on. If you”re

on Windows, UltraEdit can do most of the things you”d like. And don”t rely

on a software to correct human behaviours ^_^.
