I have a script that creates a folder foo-12345. Issue is, the numbers in the folder change name anytime I run a per script that creates it. I'm trying to find a way to change directory into the folder so I can do a search. I tried using a variable:
import os
output = /var/foo-*
os.chdir(ouput)
This does not seem to work. Is there a way to capture that folder name in a variable and use that variable instead?
You can use the glob module to do it.
import glob
dirs = glob.glob('/var/foo-*')
The resulting dirs is a list, so you will need to process it as such. Have a look at the documentation

I am trying to load some assets onto my program that I have them in a folder called 'Graphics', which is inside the folder 'Snake', which is inside the folder 'Projects', which is inside the folder 'Python'. However, also inside that folder 'Python' is another folder named 'HelloWorld'.
I am trying to load some assets in a program that I am running in 'Snake' and Python is searching for the assets in the 'HelloWorld' folder (which is where I used to keep my python files).
I get the error:
FileNotFoundError: No file 'Projects/Snake/Graphics/apple.png' found in working directory 'C:\Users\35192\OneDrive - WC\Desktop\Python\HelloWorld'
I believe that for this I have to change the default directory for vs code. I have changed the default directory for the command prompt and it did nothing. Perhaps this is because the python that I am running in the command prompt is different from the one in vs code (?)
How do I fix this?
Thank you in advance.
Edit:
This is how I am currently loading the image:
apple = pygame.image.load('Projects\Snake\Graphics\apple.png').convert_alpha()
Use pathlib to construct the path to your images. You wil have to add import pathlib to your code.
pathlib.Path(__file__) will give you the path to the current file. pathlib.Path(__file__).parent will give you the folder. Now you can construct the path with the / operator.
Try the following code and check the output.
import pathlib
print(pathlib.Path(__file__))
print(pathlib.Path(__file__).parent)
print(pathlib.Path(__file__).parent / 'Grahics' / 'apple.png')
Now you will be able to move the full project to a totally different folder without having to adjust any code.
Your code example looks like this: apple = pygame.image.load('Projects\Snake\Graphics\apple.png').convert_alpha()
If you import pathlib you can replace that with the dynamic approach:
path_to_image= pathlib.Path(__file__).parent / 'Grahics' / 'apple.png'
apple = pygame.image.load(path_to_image).convert_alpha()
I'm quite sure that pygame can work with a path from pathlib. If not then you have to convert the path to a string manually
apple = pygame.image.load(str(path_to_image)).convert_alpha()
You don't need to change the default directory. Just load from the full directory. That should look something like: "C:\Users\...\Python\Snake\Graphics\apple.png".
I think the simplest way is to first see your active directory by simply typing in
pwd, and then you could simply change the directory by cd("C:/path/to/location"), remember you have to use the backslash, or just use the following library:
import os
os.chdir("C:/path/to/location")
As pydragon posted, you could also import it by just giving the import function a path.
So, i have a variable, for example dir = "Crypter.aes". I need to variable like dir, but without .aes. What gotta I do for that? I use directory parser, that make many dir with file name in that directory, and for each file I need to remove a certain part at the end - .aes
This is a task for the os.path module in the standard library.
import os.path
dir, _ = os.path.splitext("Crypter.aes")
If you're working a lot with file paths, you also might want to take a look at the pathlib module.
from pathlib import Path
dir = Path("Crypter.aes").stem
The goal is to run through a half stable and half variable path.
I am trying to run through a path (go to lowest folder which is called Archive) and fill a list with files that have a certain ending. This works quite well for a stable path such as this.
fileInPath='\\server123456789\provider\COUNTRY\CATEGORY\Archive
My code runs through the path (recursive) and lists all files that have a certain ending. This works well. For simplicity I will just print the file name in the following code.
import csv
import os
fileInPath='\\\\server123456789\\provider\\COUNTRY\\CATEGORY\\Archive
fileOutPath=some path
csvSeparator=';'
fileList = []
for subdir, dirs, files in os.walk(fileInPath):
for file in files:
if file[-3:].upper()=='PAR':
print (file)
The problem is that I can manage to have country and category to be variable e.g. by using *
The standard library module pathlib provides a simple way to do this.
Your file list can be obtained with
from pathlib import Path
list(Path("//server123456789/provider/".glob("*/*/Archive/*.PAR"))
Note I'm using / instead of \\ pathlib handles the conversion for you on windows.
I am trying to make a program that will go through and visit an array of directories and run a program and create a file inside.
I have everything working except that I need to figure out a way to import from a new path each time to get to a new directory.
For example:
L =["directory1", "directory2", "directory3"]
for i in range(len(L)):
#I know this is wrong, but just to give an idea
myPath = "parent."+L[i]
from myPath import file
#make file... etc.
Obviously when I use myPath as a variable for the path to import, I get an error. I have tried several different ways by searching online through Stack Overflow and reading OS and Sys documentation, but have come to no working result.
You can use 'imp' module to load source code of python scrips
import imp
root_dir = '/root/'
dirs =["directory1", "directory2", "directory3"]
for _dir in dirs:
module_path = os.path.join(root_dir,_dir,'module.py')
mod = imp.load_source("module_name", module_path)
# now you can call function in regular way, like mod.some_func()
I want to create a text file inside each directory. To do this I must
cycle through my array and take each directory name so I can visit it.
import is for loading external modules, not creating new files, if creating new files is what you want to do, use the open statement, and open the not yet existing file with 'w' mode. Note: the directory must exist.
from os.path import join
L =["directory1", "directory2", "directory3"]
for d in L: # loop through the directories
with open(join(d,"filename.txt"), "w") as file:
pass # or do stuff with the newly created file
I'm new to Python and really want this command to work so I have been looking around on google but I still can't find any solution. I'm trying to make a script that deletes a folder inside the folder my Blender game are inside so i have been trying out those commands:
import shutil
from bge import logic
path = bge.logic.expandPath("//")
shutil.rmtree.path+("/killme") # remove dir and all contains
The Folder i want to delete is called "killme" and I know you can just do: shutil.rmtree(Path)
but I want the path to start at the folder that the game is in and not the full C:/programs/blabla/blabla/test/killme path.
Happy if someone could explain.
I think you are using shutil.rmtree command in wrong way. You may use the following.
shutil.rmtree(path+"/killme")
Look at the reference https://docs.python.org/3/library/shutil.html#shutil.rmtree
Syntax: shutil.rmtree(path, ignore_errors=False, onerror=None)
Assuming that your current project directory is 'test'. Then, your code will look like the follwing:
import shutil
from bge import logic
path = os.getcwd() # C:/programs/blabla/blabla/test/
shutil.rmtree(path+"/killme") # remove dir and all contains
NOTE: It will fail if the files are read only in the folder.
Hope it helps!
What you could do is set a base path like
basePath = "/bla_bla/"
and then append the path and use something like:
shutil.rmtree(basePath+yourGamePath)
If you are executing the python as a standalone script that is inside the desired folder, you can do the following:
#!/usr/bin/env_python
import os
cwd = os.getcwd()
shutil.rmtree(cwd)
Hope my answer was helpful
The best thing you could do is use the os library.
Then with the os.path function you can list all the directories and filenames and hence can delete/modify the required folders while extractring the name of folders in the same way you want.
for root, dirnames, files in os.walk("issues"):
for name in dirnames:
for filename in files:
