I am very new to Python as well a programming, and I would like to slice the folder path. For example, if my original path is:
C:/Users/arul/Desktop/jobs/project_folder/shots/shot_folder/elements/MexicoCity-Part1/
I would like to get the path like this:
C:/Users/arul/Desktop/jobs/project_folder/shots/shot_folder/
What are the methods of doing this in Python?
You could use the pathlib module:
from pathlib import Path
pth = Path('C:/Users/arul/Desktop/jobs/project_folder/shots/shot_folder/')
print(pth)
print(pth.parent)
print(pth.parent.parent) # C:/Users/arul/Desktop/jobs/project_folder
The module has a lot more of very convenient methods for handling paths: your problem could also be solved using parts like this:
print('/'.join(pth.parts[:-2]))
In Python 2.7 you could build your own parts function using os.path:
from os import path
pth = 'C:/Users/arul/Desktop/jobs/project_folder/shots/shot_folder/'
def parts(pth):
ret = []
head, tail = path.split(pth)
if tail != '':
ret.append(tail)
while head != '':
head, tail = path.split(head)
ret.append(tail)
return ret[::-1]
ret = path.join(*parts(pth)[:-2])
print(ret) # C:/Users/arul/Desktop/jobs/project_folder
If you just want to split on elements, then use this.
>>> path = 'C:/Users/arul/Desktop/jobs/project_folder/shots/shot_folder/elements/MexicoCity-Part1/'
>>> path.split('elements')[0]
'C:/Users/arul/Desktop/jobs/project_folder/shots/shot_folder/'
One drawback of this approach is that it'll fail if you encounter the word elements in your path multiple times. In that case, you can do something like:
>>> '/'.join(path.split('/')[:-3]) + '/'
'C:/Users/arul/Desktop/jobs/project_folder/shots/shot_folder/'
Assuming you know the depth of the path you need.
You can do something like this:
folder = 'C:/Users/arul/Desktop/jobs/project_folder/shots/shot_folder/elements/MexicoCity-Part1/'
folder.rsplit('/', 3)[0]
str.rsplit() basically returns a list of the words in the string, separated by the delimiter string (starting from right).
Please have a look at documentation for more details on this method.
