How to use data files of sub-directories and perform iterative operation in python

I have my jupyter notebook (python script) in current directory. In current directory, I have two subfolders, namely a and b. In both directories a and b I have equal number of .dat files with same names. For example, directory a contains files, namely x1-x1-val_1, x1-x1-val_5, x1-x1-val_11...x1-x1-val_86 and x1-x2-val_1, x1-x2-val_5, x1-x2-val_11...x1-x2-val_86, i.e. values are in range(1,90,5). Likewise I have files in directory b.
I want to use my python script to access files in a and b to perform iterative operations on .dat files. My present code works only if I keep files of directory a or b in current directory. For example, my script uses following function.
def get_info(test):
my_dict = {'test':test}
c = []
for i in range(1,90,5):
x_val = 'x_val_'+test+'-val_'+str(i)
y_val = 'y_val_'+test+'-val_'+str(i)
my_dict[x_val],my_dict[y_val]= np.loadtxt(test+'-val_'+str(i)+'.dat'
,usecols= (1,2),unpack=True)
dw = compute_yy(my_dict[x_val],my_dict[y_val],test)
c.append(dw)
my_dict.update({test+'_c'+:np.array(c)})
return my_dict
I call get_info() by using following:
tests = ['x1-x1', 'x1-x2']
new_dict = {}
for i in tests:
new_dict.update({i:get_info(i)})
How can I use my code to access files in either directory a and/or b? I know its about providing correct path, but I am unsure how can I do so. One way I thought is following;
ext = '.dat'
for files in os.listdir(path_to_dir):
if files.endswith(ext):
print(files) # do operations
Alternative could be to make use of os.path.join(). However, I am unable to solve it such that I can use same python script (with minimum changes perhaps) that can use files and iterate on them which are in subfolders a and b. Thanks for your feedback in advance!

If you want to run get_info() on every folder separatelly then you have two methods:
First: described by #medium-dimensional in comment
You can use os.chdir(folder) to change Current Working Directory. And then code will run with files in this folder
You can see current working directory with print( os.getcwd() )
os.chdir("a")
get_info(i)
os.chdir("..") # move back to parent folder
os.chdir("b")
get_info(i)
os.chdir("..") # move back to parent folder
chdir() (similar to command cd in console) can use relative path (r"a") full path (r"C:\full\path\to\a") and .. to move to parent folder (r"a\..\b")
If files can be in nested folders then .. may not go back you can use getcwd()
cwd = os.getcwd()
os.chdir("folder1/folder2/a")
get_info(i)
os.chdir(cwd) # move back to previous folder
os.chdir("folder1/folder2/b")
get_info(i)
os.chdir(cwd) # move back to previous folder
(BTW: in console on Linux you can use cd - to move back to previous folder)
Second: use folder when you open file
Every command which gets filename can also get path with folder\filename (it can be relative path, full path, and path with ..) like
r"a\filename.dat"
r"C:\full\path\to\b\filename.dat"
r"a\..\b\filename.dat"
So you could define function with extra option folder
def get_info(text, folder):
and use this folder when you read file
loadtxt(folder + r'\' + test+'-val_'+str(i)+'.dat', ...)
or more readable with f-string
loadtxt(rf'{folder}\{test}-val_{i}.dat', ...)
And later you run it as
get_info(i, "a")
get_info(i, "b")

Move Files from a Directory to Another Based on a Condition

I have a main directory that contains multiple folders. I wanna loop through these sub folders, check for each sub folder if it contains more than (e.g. 10 files) keep the 10 files and move the rest to a new directory, otherwise delete the subfolder.
This is how my directory looks like:
Each sub directory contains around 100 files, I wanna loop through these sub directories, do a check first, keep 10 files, and move the rest to a new directory.
I would presume that this can be done with the help of pathlib or os but I need a help in writing the script.
I think the code will be something like the following:
for directory in os.listdir('path'):
for file in os.listdir(os.path.join('path', directory)):
if(....){
# keep 10 files and move the rest to a new directory
} else {
# delete the subdir
}

I suggest to use shutil library for moving and removing files and directories, below is an example for moving a file from a path to another path:
import shutil
original = r'original_path_where_the_file_is_currently_stored\file_name.file_extension'
target = r'target_path_where_the_file_will_be_moved\file_name.file_extension'
shutil.move(original,target)
And below is an example for removing a directory including all it's content:
import shutil
dirPath = '/path_to_the_dir/name_of_dir/'
shutil.rmtree(dirPath)
We use the two snippets above to create the final code:
import shutil
import os
new_dir_path = "path_to_the_new_dir/new_dir_name"
for directory in os.listdir('path'):
for index, file in enumerate(file_list := os.listdir(path_dir := os.path.join('path', directory))):
if(len(file_list) >= 10):
# keep 10 files and move the rest to a new directory
if(index > 9):
shutil.move(os.path.join(path_dir,file),os.path.join(new_dir_path,file))
else:
# delete the subdir
shutil.rmtree(path_dir)

Moving first file in folder to another folder

I am trying to move the first file in a folder into another folder using python. I am using shutil in order to do this.
I know that the following will move the whole S folder into the D folder. but how do I choose only the first file within the folder?
S = '/Users/kitchensink/Desktop/Sfolder'
D = '/Users/kitchensink/Desktop/Dfolder'
shutil.move(S, D)
print("moved")

You can use glob to find the files in a folder. For example if you want to have a list with all files in SFolder you can do this:
import glob
s_files = glob.glob('/Users/kitchensink/Desktop/Sfolder/*')
To get the first file, simply take the first element from s_files.
After this you can still use shutil to do the actual moving.

Move files one by one to newly created directories for each file with Python 3

What I have is an initial directory with a file inside D:\BBS\file.x and multiple .txt files in the work directory D:\
What I am trying to do is to copy the folder BBS with its content and incrementing it's name by number, then copy/move each existing .txt file to the newly created directory to make it \BBS1, \BBS2, ..., BBSn (depends on number of the txt).
Visual example of the Before and After:
Initial view of the \WorkFolder
Desired view of the \WorkFolder
Right now I have reached only creating of a new directory and moving txt in it but all at once, not as I would like to. Here's my code:
from pathlib import Path
from shutil import copy
import shutil
import os
wkDir = Path.cwd()
src = wkDir.joinpath('BBS')
count = 0
for content in src.iterdir():
addname = src.name.split('_')[0]
out_folder = wkDir.joinpath(f'!{addname}')
out_folder.mkdir(exist_ok=True)
out_path = out_folder.joinpath(content.name)
copy(content, out_path)
files = os.listdir(wkDir)
for f in files:
if f.endswith(".txt"):
shutil.move(f, out_folder)
I kindly request for assistance with incrementing and copying files one by one to the newly created directory for each as mentioned.
Not much skills with python in general. Python3 OS Windows
Thanks in advance

Now, I understand what you want to accomplish. I think you can do it quite easily by only iterating over the text files and for each one you copy the BBS folder. After that you move the file you are currently at. In order to get the folder_num, you may be able to just access the file name's characters at the particular indexes (e.g. f[4:6]) if the name is always of the pattern TextXX.txt. If the prefix "Text" may vary, it is more stable to use regular expressions like in the following sample.
Also, the function shutil.copytree copies a directory with its children.
import re
import shutil
from pathlib import Path
wkDir = Path.cwd()
src = wkDir.joinpath('BBS')
for f in os.listdir(wkDir):
if f.endswith(".txt"):
folder_num = re.findall(r"\d+", f)[0]
target = wkDir.joinpath(f"{src.name}{folder_num}")
# copy BBS
shutil.copytree(src, target)
# move .txt file
shutil.move(f, target)

Import list of folder names in a folder with Python

So I've started down the path again of trying to automate something. My end game is to combine the data within Excel files containing the Clean Up in the file name and combine the data from a tab within these files named LOV. So basically it had to go into a folder with folders which have folders again that have 2 files, one file has the words Clean Up in the naming and is a .xlsx file. Which I need to only read those files and and pull the data from the tab called LOV into one large file. --- So that's my end goal. Which I just started and I am no where near, but now you know the end game.
Currently I'm stuck just getting a list of Folder names in the Master folder so I at least know it's getting there lol.
import os
import glob
import pandas as pd
# assigns directory location to PCC Folder
os.chdir('V:/PCC Clean Up Project 2017/_DCS Data SWAT Project/PCC Files
Complete Ready to Submit/Brake System Parts')
FolderList = glob.glob('')
print(FolderList)
Any help is appreciated, thanks guys!

EDITED
Firstly Its hard to understand your question. But from what I understand you need to iterate over folders and subfolders, you can do that with
for root, dirs, files in os.walk(source): #Give your path in source
for file in filenames:
if file.endswith((".xlxs")): # You can check for any file extension
filename = os.path.join(subdir,file)
dirname = subdir.split(os.path.sep)[-1] # gets the directory name
print(dirname)

If you only want the list of folders in your current directory, you can use os.path. Here is how it works:
import os
directory = "V:/PCC Clean Up Project 2017/_DCS Data SWAT Project/PCC Files
Complete Ready to Submit/Brake System Parts"
childDirectories = next(os.walk(directory))[1]
This will give you a list of all folders in your current directory.
Read more about os.walk here.
You can then go into one of the child directories by using os.chdir:
os.chdir(childDirectories[i])
