I'm using Python 2.7 sockets to receive data开发者_如何学运维:
data = self.socket.recv(4096)
How do I go about retrieving the first unsigned short from the data? The data looks like this:
>>> print repr(data)
'\x00\x053B2D4C24\x00\x00\x01\x00...'
If by unsigned short you mean two bytes, just do:
data[:2]
If you know and expect a certain chunk size of data to parse, you can use the struct
library.
This is what I came up with:
s = struct.Struct('H')
num = int('0x' + ''.join(x for x in repr(packet[:s.size]) if x.isdigit()), 0)
Old question but thought I'd post a better solution anyway:
value, = struct.unpack('H', data[:2])
Note the ,
usage in order to correctly unpack the 1-tuple that is returned.
