Python与C＃中的FileStream等效吗？

Question

I am trying to replicate this bit of code in Python which takes a text stream encoded in base64 and writes it byte by byte to a csv file:

using (FileStream localFileStream = new FileStream(destinationPath, FileMode.Create, FileAccess.Write))
{
   using (Stream remoteStream = client.DownloadFile(jobId))
   {
     while (!endOfStream)
     {
         bytesRead = remoteStream.Read(buffer, 0, buffer.Length);
         if (bytesRead > 0)
         {
              localFileStream.Write(buffer, 0, bytesRead);
              totalBytes += bytesRead;
         }
         else
         {
              endOfStream = true;
         }
      }
   }
}

Unfortunately I do not know what the equivalent of FileStreamis in Python, so I am unable to translate the code.

Answer 1

The equivalent to C#'s FileStream is Python's file object. They both handle reading & writing files, and do not do any major manipulation of the data read/written. (I'm not sure what a "coded download text stream" is, but neither language's file writer is going to decode it on its own.)

(When opened in text mode, Python's file object will normalize line endings, but that's it.)
