How I could split this:
C:\my_dir\repo\branch
to:
['C:\my_dir', rest_part_of_string]
where rest_part_of_string can be one string or could be splitted every \. I don't care about rest, i just want first two elements together.

use raw strings?? r"C:\my_dir\repo\branch" linkPythonTester– PythonTester2015-08-04 15:31:37 +00:00Commented Aug 4, 2015 at 15:31

python 3.4 has methods for that (note the forward slashes instead of the backslashes (or double the backslashes))
# python 3.4
from pathlib import Path
p = Path('C:/my_dir/repo/branch')
print(p.parent)
print(p.name)
for what you need parts is interesting:
print(p.parts)
# -> ('C:', 'my_dir', 'repo', 'branch')
print('\\'.join(p.parts[:2]), ' -- ', '\\'.join( p.parts[2:]))
# -> C:\my_dir -- repo\branch
in python 2.7 this needs a bit more work:
import os
p = 'C:/my_dir/repo/branch'
def split_path(path):
parts = []
while 1:
path, folder = os.path.split(path)
if folder:
parts.append(folder)
else:
if path:
parts.append(path)
break
parts.reverse()
return parts
parts = split_path(p)
print('\\'.join(parts[:2]), ' -- ', '\\'.join(parts[2:]))
# -> C:\my_dir -- repo\branch
Using regular expression (re module documentation):
>>> import re
>>> print(re.match(r'[^\\]+\\[^\\]+', r'C:\my_dir\repo\branch').group())
C:\my_dir
>>> re.findall(r'[^\\]+\\[^\\]+|.+', r'C:\my_dir\repo\branch')
['C:\\my_dir', '\\repo\\branch']

Yeah, but i have to wait about 1 hour before i can do it. And yesterday i had no access to SO. Thanks :)
you could split the path on \ and rejoin based on index:
>>>my_path = r'C:\my_dir\repo\branch'
>>>split_path = ["\\".join(my_path.split("\\")[:2]), "\\".join(my_path.split("\\")[2:])]
['C:\\my_dir', 'repo\\branch']
>>> first, last = "\\".join(x.split("\\")[:2]), "\\".join(x.split("\\")[2:])
>>> print first, last
C:\my_dir repo\branch

You need os.path.dirname() (or os.path.split), applied recursively or iteratively, until you cannot go up in the directory hierarchy further.
In general the functions provided by os.path should work better that re-invented wheels, due to better cross-platform support. There are a large number of primitives from which you can build your own path-manipulating function.
