I wanted to convert an object of type bytes to binary representation in python 3.x. For example, I want to convert the bytes object b'\x11' to the binary representation 00010001 in binary (or 17 in decimal). I tried this: print(struct.unpack("h","\x11")) But I'm getting: error struct.error: unpack requires a bytes object of length 2 Starting from Python 3.2, you can use int.from_bytes . Second argument, byteorder , specifies endianness of your bytestring. It can be either 'big' or 'little' . You can also use sys.byteorder to get your host machine's native byteorder. import sys int.from_bytes(b

I use okhttp library for download files in android. I download successfully. But something is wrong when I pause and resume download. Response request = new Request.Builder().url(url).build(); ResponseBody responseBody = response.body(); File file = new File(filePath); BufferedInputStream input = new BufferedInputStream(responseBody.byteStream()); OutputStream output; if (isResume) { output = new FileOutputStream(file, true); input.skip(downloadedSize); } else { output = new FileOutputStream(file, false); } long totalByteSize = responseBody.contentLength(); byte[] data = new byte[1024]; int

I have a string of several hundred bytes and some Int32 values. I want to write these to a file, verbatim. I have tried many suggested solutions and none have worked for me. I get extraneous brackets or spaces or commas in the file. Can anyone suggest a simple, reliable solution? I thought my question was very clear, but after reading the comments, I have simplified it. How do I write and/or append "12345" to a file so that the file contains the following Hex values: 3132333435 ? The best result I can obtain is <3132333435>, by writing an NSData string. I can get the desired result using this

I have 3 machines: server where the file is located server where REST service is running ( Jersey) client(browser) with access to 2nd server but no access to 1st server How can I directly (without saving the file on 2nd server) download the file from 1st server to client's machine? From 2nd server I can get a ByteArrayOutputStream to get the file from 1st server, can I pass this stream further to the client using the REST service? It will work this way? So basically what I want to achieve is to allow the client to download a file from 1st server using the REST service on 2nd server (since
