does anyon want to write an untabify command?

i was expecting some existing function that just does it.

Yes with your none exciting effort,you should except that

i like that in_place module. too bad i can't assume every python installation has it. and i wish they would quit naming things with CamelCase.

There is a option in standard library fileinput with inplace=True,but it not so nice to use,in-place module dos it better and are simpler to use.

As mention all code is there,here taken out.

import re
import in_place

def tab_space(text, tabs=8):
    result = ''
    for c in text:
        if c == '\t':
            result += ' '
            while len(result) % tabs != 0:
                result += ' '
        else:
            result += c
    return result

def tab_even(file, space=4):
    with in_place.InPlace(file) as f:
        text = f.read()
        result = re.sub(r'\s\s+|\t', ' '*space, text)
        f.write(result)

if __name__ == '__main__':
    #--- Tab space ---#
    file = 'file_1.txt'
    tabs = 4
    with in_place.InPlace(file) as f_out:
        for line in f_out:
            line = tab_space(line, tabs)
            f_out.write(line)

    #--- Even Space ---#
    #file = 'file_1.txt'
    #tab_even(file, space=8)

Test file file_1.txt.

Output:
One	Two	Three	Four	Five	six	seven
One	Two	Three	Four	Five	six	seven
One	Two	Three	Four	Five	six	seven
