pointer typecasting like c in python

问题

I've a c code to type cast a string to an integer via pointer.

char s[]="efgh";
int * p;
p=(int *) s;
printf("%d",*p);

This gives me an output of:

1751606885

Which is a 32 bit integer.

I'm analyzing a network packet in python and need the above functionality in python. I've a string

s="efgh"

and want the above in a 32 bit integer (from the byte level).

How can I do it?

回答1:

You can try struct.unpack:

>>> import struct
>>>
>>> struct.unpack('<I', 'efgh')
(1751606885,)
>>>
