RuntimeError: Bad password for file

Question

With python's zipfile module, I could not open a encrypted zip file and I found out that the compression type is 99. I could open it with WinZip but I would like to automate the procedure with python.

Should I consider using 7zip's command line or is there some way in zipfile module itself to solve the problem? Thanks!

      3         print (info.filename, info.date_time, info.file_size, info.compress_type)
      4     myzip.setpassword(b'password')
      5     with myzip.open('641903.txt','r') as myfile:<-----
      6         print(myfile.readline()

641903.txt (2018, 6, 26, 11, 59, 50) 342 99

Answer 1

You can open password-protected files by simply adding a third parameter

    with myzip.open('641903.txt','r', 'password') as myfile:
        print(myfile.readline()
