Introduction to how to simply implement subnet mask conversion in Python

The example in this article describes how to simply implement subnet mask conversion in Python. Share it with everyone for your reference, the details are as follows:

Here, the subnet mask length is converted into a specific subnet mask address:

def exchange_maskint(mask_int):
  bin_arr = ['0' for i in range(32)]
  for i in range(mask_int):
    bin_arr[i] = '1'
  tmpmask = [''.join(bin_arr[i * 8:i * 8 + 8]) for i in range(4)]
  tmpmask = [str(int(tmpstr, 2)) for tmpstr in tmpmask]
  return '.'.join(tmpmask)
if __name__ == '__main__':
  print exchange_maskint(24)
