I have the directory, where I have to store all the items separately in the list of folders. This list includes exactly the same folders only with incrementing number, as you can see below:

enter image description here

Because I am going to have more than 200 folders, I decided to create all of them by using Python console in QGIS.

My approach so far looks as you can see below:

 import os
 path='C:\\Users\\mk\\Desktop\\AX\\Pre survey\\Tyton'
 for i in range (1,208):
 Newfolder='Strand-' + str(i)

As per the tutorial below:


Since I managed to create one folder, there is a problem with the batch of these folders.

First of all, I cannot put something like "leading 0", as I tried:

    for i in range (001,208)

I cannot do this, but I need the folder numeration as shown in the image.

Another issue is, that if I use the whole code presented, Python throws an error:

IndentationError: expected an indented block

debugging the following line:

    Newfolder='Strand-' + str(i)

The examples how to solve this error are here:



but i couldn't apply them to my situation.

How can I do the batch directory creation with Python, preferably by QGIS python console?

Try this:

import os
path='C:\\Users\\mk\\Desktop\\AX\\Pre survey\\Tyton\\'
for i in range (1,208):
    newfolder=path + 'Strand-' + str(format(i, '03'))

About your errors:

  • Nothing happens. Maybe is something to add?

  • OK I see that it works, but the path is slightly wrong, as the folders aren't created at the path: path='C:\\Users\\mk\\Desktop\\AX\\Pre survey\\Tyton\\' but here: path='C:\\Users\\mk\\Desktop\\AX\\Pre survey\\' it's simply one folder up. What is missing here then?

    Yes! I found an error! I forgot about \\ at the very end of my path. hence Python saved my folders in one level up and added the Tyton prefix. Thanks a lot!
