python怎么处理二进制流

binascii.b2a_hex(data)
binascii.hexlify(data)
Return the hexadecimal representation of the binary data. Every byte of data is converted into the corresponding 2-digit hex representation. The resulting string is therefore twice as long as the length of data.
binascii.a2b_hex(hexstr)
binascii.unhexlify(hexstr)
Return the binary data represented by the hexadecimal string hexstr. This function is the inverse of b2a_hex(). hexstr must contain an even number of hexadecimal digits (which can be upper or lower case), otherwise a TypeError is raised.
