python实现将IP地址转换为数字

话不多说，直接代码

ip_addr='192.168.2.10'

# transfer ip to int
def ip2long(ip):
    ip_list=ip.split('.')
    result=0
    for i in range(4):  #0,1,2,3
        result=result+int(ip_list[i])*256**(3-i)
    return result

long=3232236042

# transfer int to ip
def long2ip(long):
    floor_list=[]
    yushu=long
    for i in reversed(range(4)):   #3,2,1,0
        res=divmod(yushu,256**i)
        floor_list.append(str(res[0]))
        yushu=res[1]
    return '.'.join(floor_list)

a=long2ip(long)
print(a)
