Sorry for the stupid question but,
I read the documentation and still can understand what is this function doing:
struct.pack('<L',0x01D1F23A)
Can someone explain in very childish and detailed manner what this function will do for the given input and for other inputs.
When i print the output i got ":≥╤☺", an ASCII representation of the hex values, so basically how struct.pack is hanging the hex value beside that it turns it to little endian. How does it stored in memory ? I didn't understand what does it "pack's".
Thanks.
The return value of this is a bytestring (in Python 3), or a standard (non-unicode) string in Python 2, showing 0x01D1F23A represented as an unsigned long in little-endian byte order.
It's "packed" inasmuch as it's stored as raw binary content -- the exact same content you'd have with a native unsigned long type stored natively in memory on a little-endian platform.
The byte order is specified by the <, and the unsigned-long type is specified by the L.
This is useful if you're trying to write a file, a network packet, or other content in a native binary format.
