How to compress folders using zipfile?

Question

My program so far is successfully able to add and compress files which are present in the same directory as test.py but there is also a folder named location in the same directory which contains additional files say citynames.txt What happens is when I do a simple zip.write (The logic used in else block) location is added to the zip file however its empty that is it does not contain citynames.txt inside it for some reason please help me add the folder itself somehow?

import os
import zipfile
import shutil
dir_path = os.path.dirname(os.path.realpath(__file__))  #holds the directory where script is located
os.chdir(dir_path)                                      #Changes to directory where script is located
fp=os.listdir(dir_path)                                 #file pointer

directory_size=len(os.listdir(dir_path))

zip1=zipfile.ZipFile('Archive.zip','w')

for i in range(directory_size) :
   if fp[i]=='test.py':
      break
   if fp[i]=='location':
      #Some code needs to be added here to write all the contents of folder "location" into 
       "Archive.zip"

   else:
       zip1.write(fp[i],compress_type=zipfile.ZIP_DEFLATED)

print("Process completed")

Assuming location has further sub-folders how to zip the files inside them aswell?

Listing [Python 3.Docs]: zipfile - Work with ZIP archives.

The (main) problem in your code is that you're mistaking continue by break. That way, when test.py is encountered, all the items after it will be ignored, as break exits the loop.

Here's a variant that recurses into subdirectories using [Python 3.Docs]: glob.iglob(pathname, *, recursive=False) and adds files in the archive.

code00.py:

#!/usr/bin/env python

import sys
import os
import glob
import zipfile


def main(*argv):
    archive_name = "archive.zip"
    dir_path = os.path.dirname(os.path.realpath(__file__))
    dir_path_len = len(dir_path) + len(os.path.sep)
    with zipfile.ZipFile(archive_name, mode="w", compression=zipfile.ZIP_DEFLATED) as zf:
        for file_name in glob.iglob(os.path.join(dir_path, "**"), recursive=True):
            if os.path.isdir(file_name):
                continue
            member_name = file_name[dir_path_len:]
            if member_name in [
                os.path.basename(__file__),
                archive_name,
            ]:
                continue
            print(member_name)
            zf.write(file_name, member_name)


if __name__ == "__main__":
    print("Python {0:s} {1:d}bit on {2:s}\n".format(" ".join(item.strip() for item in sys.version.split("\n")), 64 if sys.maxsize > 0x100000000 else 32, sys.platform))
    main(*sys.argv[1:])
    print("\nDone.")

Output:
