I’m converting my python script to an exe using pyinstaller –onefile -w script.py.
However, after the conversion I tried to run the script but it duplicates itself multiple times.

I did the same half a year ago, but I updated my version of the code, hence I have to do it again, but whatever I do, it always runs in duplicate.

It could be that it has to do with my subprocess piece of code:

zip_files = [f for f in os.listdir(data_analysis_folder) if f.endswith(".zip")  # file should end with .zip as extension
             and os.path.getsize(os.path.join(data_analysis_folder, f)) > 2048]  # should be bigger than 2kb to convert

zip_files_zipped = len(zip_files)
errors = []
for zip_file in zip_files:
    file_path = os.path.join(data_analysis_folder, zip_file)
    result = subprocess.Popen([program, "x", "-y", "-p" + password_customer, file_path, "-o" + data_analysis_folder],
                             stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL)
    result.wait()
    # The -y argument in the subprocess run confirms the replacement of the files automatically

    if result.returncode != 0:
        print(f"Error extracting {zip_file}: {result.stderr}")
        errors.append(f'Error extracting {zip_file}: {result.stderr}')
        errors_df = pd.DataFrame(errors)
        errors_df.to_csv(data_analysis_folder + str("/errors_zipping.csv"), index=False, decimal=",")

Does anybody has an idea of why this could happen?

Thanks,
