Here is another relatively simple solution that:

does not use dirname() (which does not work as expected on one level arguments like "file.txt" or relative parents like "..")
does not use abspath() (avoiding any assumptions about the current working directory) but instead preserves the relative character of paths

it just uses normpath and join:

def parent(p):
    return os.path.normpath(os.path.join(p, os.path.pardir))

# Example:
for p in ['foo', 'foo/bar/baz', 'with/trailing/slash/', 
        'dir/file.txt', '../up/', '/abs/path']:
    print parent(p)

Result:

.
foo/bar
with/trailing
dir
..
/abs

os path abspath doesn t validate anything  so if we re already appending strings to   file   there s no need to bother with dirname or joining or any of that  Just treat   file   as a directory and start climbing     climb to   file   s parent s parent  os path abspath   file                  That s far less convoluted than os path abspath os path join os path dirname   file           and about as manageable as dirname dirname   file      Climbing more than two levels starts to get ridiculous   But  since we know how many levels to climb  we could clean this up with a simple little function   uppath   lambda  path  n  os sep join  path split os sep   -n        file       aParent templates blog1 page html   gt  gt  gt  uppath   file    1    aParent templates blog1   gt  gt  gt  uppath   file    2    aParent templates   gt  gt  gt  uppath   file    3    aParent

I think use this is better   os path realpath   file    rsplit      X  0    In  1     file       aParent templates blog1 page html   In  2   os path realpath   file    rsplit      3  0  Out 3     aParent   In  4     file       aParent templates blog1 page html   In  5   os path realpath   file    rsplit      1  0  Out 6     aParent templates blog1   In  7   os path realpath   file    rsplit      2  0  Out 8     aParent templates   In  9   os path realpath   file    rsplit      3  0  Out 10     aParent

os pardir is a better way for     and more readable    import os print os path abspath os path join given path  os pardir       This will return the parent path of the given path

You can apply dirname repeatedly to climb higher  dirname dirname file    This can only go as far as the root package  however  If this is a problem  use os path abspath  dirname dirname abspath file

os path dirname os path abspath   file       Should give you the path to a   But if b py is the file that is currently executed  then you can achieve the same by just doing  os path abspath os path join  templates    blog1    page html

Use relative path with the pathlib module in Python 3 4    from pathlib import Path  Path   file    parent   You can use multiple calls to parent to go further in the path   Path   file    parent parent   As an alternative to specifying parent twice  you can use   Path   file    parents 1

Use the following to jump to previous folder   os chdir os pardir    If you need multiple jumps a good and easy solution will be to use a simple decorator in this case
