Python字符串到字节的转换

Question

x = '192.168.1.1'
y = '255.255.255.0'
a = x.split('.')
b = y.split('.')
a[0] & b[0]

Traceback (most recent call last):

File "<pyshell#35>", line 1, in <module>
a[0] & b[0]
TypeError: unsupported operand type(s) for &: 'str' and 'str'

Please help, I'd like to have the result of and-ing process between 192 and 255, between 168 and 255. How can I do that?

Answer 1

you need to convert the strings to integers and & those together

however on of the properties of 255 is that it is eight 1 s so anding it together with a smaller number is always equal to the other number

Answer 2

You need to first convert the strings into integers. Try this:

x = '192.168.1.1'
y = '255.255.255.0'
a = [int(elem) for elem in x.split('.')]
b = [int(elem) for elem in y.split('.')]
a[0] & b[0]
