Extract files from zip without keeping the structure using python ZipFile?

Question

I try to extract all files from .zip containing subfolders in one folder. I want all the files from subfolders extract in only one folder without keeping the original struc

Answer 1

Just extract to bytes in memory,compute the filename, and write it there yourself, instead of letting the library do it - -mostly, just use the "read()" instead of "extract()" method:

Python 3.6+ update(2020) - the same code from the original answer, but using pathlib.Path, which ease file-path manipulation and other operations (like "write_bytes")

from pathlib import Path
import zipfile
import os

my_dir = Path("D:\\Download\\")
my_zip = my_dir / "my_file.zip"

zip_file = zipfile.ZipFile(my_zip, 'r')
for files in zip_file.namelist():
    data = zip_file.read(files, my_dir)
    myfile_path = my_dir / Path(files.filename).name
    myfile_path.write_bytes(data)
zip_file.close()

Original code in answer without pathlib:

import zipfile
import os

my_dir = "D:\\Download\\"
my_zip = "D:\\Download\\my_file.zip"

zip_file = zipfile.ZipFile(my_zip, 'r')
for files in zip_file.namelist():
    data = zip_file.read(files, my_dir)
    # I am almost shure zip represents directory separator
    # char as "/" regardless of OS, but I  don't have DOS or Windos here to test it
    myfile_path = os.path.join(my_dir, files.split("/")[-1])
    myfile = open(myfile_path, "wb")
    myfile.write(data)
    myfile.close()
zip_file.close()
