进制转换相关

#将二进制转化为十进制num = ‘0b1010111011‘v1 = int(num,base=2)print(v1)#将十六进制转化十进制num = ‘0x15646351‘v2 = int(num,base=16)print(v2)

将IP地址转化为二进制

ip=‘192.168.12.79‘v1 = ip.split(‘.‘)str = []for i in v1:    num = bin(int(i))    str.append(num)    a=‘,‘.join(str)print(a)‘‘‘注意：1.join后的函数里面的小元素必须是字符型2.默认二进制位字符型‘‘‘

ip=‘192.168.12.79‘v1 = ip.split(‘.‘)strl = []for i in v1:    num = bin(int(i))    if len(num) == 10:        num = num[2:10]    elif len(num) < 10:        v1 = 10-len(num)        num =‘0‘*v1+num[2::]    er_num=str(int(num,base=2))    strl.append(er_num)    result=",".join(strl)print(result)
