Hello ~ I'm new with python, what my problem is, I have a binary file, I want to read first 2 bytes and convert it to host byte order, then write it to another file.
I try to use 'socket' and 'struct', but somehow i can not get it working fine: for example, totally I'm not sure if my steps is correct or not: ++++++++++++++++++++++++++++++++++++++++++++++++ >>> import socket >>> f=open('a.bin','rb') >>> f.read(2) '\x04\x00' >>> f.seek(0) >>> st=f.read(2) >>> e=open('test.bin','w+b') >>> e.write(socket.ntohs(struct.unpack('H',st[:2])[0])) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: argument 1 must be string or read-only buffer, not int +++++++++++++++++++++++++++++++++++++++++++++++++ It failed due to the parameter is 'int', not 'str' in write function. but how can i do that?
