Python's method for CRC32 value _python

The example in this article describes Python's method for finding CRC32 values. Share to everyone for your reference. The implementation methods are as follows:

To ask for CRC value, import BINASCII before
Binascii.crc32 (v) The CRC32 value of V is obtained, which is a long shape, like -1456387l, which &0xffffffff the value of the value as 48a213l form.
And then the value is expressed in 16,

The specific code is as follows:

def _crc32 (self, V): "" " 
  generates the CRC32 hash of the V. 
  @return: str, the STR value for the CRC32 of the V 
  "" return 
  ' 0x%x '% (Binascii.crc32 (v) & 0xFFFFFFFF) #取crc3 2 of eight-bit data%x returns 16

I hope this article will help you with your Python programming.
