Put contents of a folder into a zip using python

I need to put the contents of a folder into a ZIP archive (In my case a JAR but they're the same thing).
Though I cant just do the normal adding every file individually, because for one... they change each time depending on what the user put in and it's something like 1,000 files anyway!
I'm using ZipFile, it's the only really viable option.
Basically my code makes a temporary folder, and puts all the files in there, but I can't find a way to add the contents of the folder and not just the folder itself.

Python allrady support zip and rar archife. Personaly I learn it form here https://docs.python.org/3/library/zipfile.html
And to get all files form that folder try somethign like
for r, d, f in os.walk(path):
for file in f:
#enter code here

Copying/pasting specific files in batch from one folder to another

I'am really new to this python scripting thing, but pretty sure, that there is the way to copy files from one folder (via given path in .txt file) to another.
there would be directly path to the folder, which contains photo files
I'am working with huge amounts of photos, which contains gps metadata (so i need not to lose it).
Really apreciate any help, thanks.

Here is a short and simple solution:
import shutil
import os
# replace file_list.txt with your files
file_list = open("file_list.txt", "r")
# replace my_dir with your copy dir
copy_dir = "my_dir"
for f in file_list.read().splitlines():
print(f"copying file: {f}")
shutil.copyfile(f, f"{copy_dir}/{os.path.split(f)[1]}")
file_list.close()
print("done")
It loops over all the files in the file list, and copies them. It should be fast enough.

prevent getfiles from seeing .DS and other hidden files

I am currently working on a python project on my macintosh, and from time to time I get unexpected errors, because .DS or other files, which are not visible to the "not-root-user" are found in folders. I am using the following command
filenames = getfiles.getfiles(file_directory)
to retreive information about the amount and name of the files in a folder. So I was wondering, if there is a possibility to prevent the getfiles command to see these types of files, by for example limiting its right or the extensions which it can see (all files are of .txt format)
Many thanks in advance!

In your case, I would recommend you switch to the Python standard library glob.
In your case, if all files are of .txt format, and they are located in the directory of /sample/directory/, you can use the following script to get the list of files you wanted.
from glob import glob
filenames = glob.glob("/sample/directory/*.txt")
You can easily use regular expressions to match files and filter out files you do not need. More details can be found from Here.
Keep in mind that with regular expression, you could do much more complicated pattern matching than the above example to handle your future needs.
Another good example of using glob to glob multiple extensions can be found from Here.
If you only want to get the basenames of those files, you can always use standard library os to extract basenames from the full paths.
import os
file_basenames = [os.path.basename(full_path) for full_path in filenames]

There isn't an option to filter within getfiles, but you could filter the list after.
Most-likely you will want to skip all "dot files" ("system files", those with a leading .), which you can accomplish with code like the following.
filenames = [f for f in ['./.a', './b'] if not os.path.basename(f).startswith('.')]

Welcome to Stackoverflow.
You might find the glob module useful. The glob.glob function takes a path including wildcards and returns a list of the filenames that match.
This would allow you to either select the files you want, like
filenames = glob.glob(os.path.join(file_directory, "*.txt")
Alternatively, select the files you don't want, and ignore them:
exclude_files = glob.glob(os.path.join(file_directory, ".*"))
for filename in getfiles.getfiles(file_directory):
if filename in exclude_files:
continue
# process the file

Check if there are .format files in a directory

I have been trying to figure out for a while how to check if there are .pkl files in a given directory. I checked the website and I could find ways to find if there are files in the directory and list them, but I just want to check if they are there.
In my directory are a total of 7 .pkl files, as soon as I create one, the others are created so to check if the seven of them exist, it will be enough to check if one exists. Therefore, I would like to check if there is any .pkl file.
This is working if I do:
os.path.exists('folder1/folder2/filename.pkl')
But I had to write one of my file names. I would like to do so without searching for a specific file. I also tried
os.path.exists('folder1/folder2/*.pkl'),
but it is not working neither as I don't have any file named *.pkl.

You can use the python module glob (https://docs.python.org/3/library/glob.html)
Specifically, glob.glob('folder1/folder2/*.pkl') will return a list of all .pkl files in folder2.

You can use :
for dir_path, dir_names, file_names in os.walk(search_dir):
# Go over all files and folders
for file_name in file_names:
if (file_name.endswith(".pkl")):
# do something like break after the first one you find
Note : This can be used if you want to search entire directory with sub directories also
In case you want to search only one directory , you can run the "for" on os.listdir(path)

Python operating on files in a folder - 'for file in folder'

I know a folder's path, and for every file in the folder I would like to do some operations. So essentially what I'm looking for is a for file in folder type of code that gives me access to the files in variables.
What is the Python way of doing this?
Thanks
EDIT - example: my folder will contain a bunch of XML files, and I have a python routine already to parse them into variables I need.

This will allow you to access and print all the file names in your current directory:
import os
for filename in os.listdir('.'):
print filename
The os module contains much more information about the various functions available. The os.listdir() function can also take any other paths you want to specify.

Does the glob library look helpful?
It will perform some pattern matching, and accepts both absolute and relative addresses.
>>> import glob
>>> for file in glob.glob("*.xml"): # only loops over XML documents
print file

For people coming at this from a python version 3.5 or later, we now have the superior os.scandir() which has tremendous performance improvements over os.listdir()
