Python Scapy and read a pcap in reverse mode

Question

I'm reading a pcap file using the rdpcap function:

s = rdpcap(pcap)

I'd like to know how to reverse s : it should be a list, but I tried with:

rev_s = s.reverse()

and it doesn't work: it gives me the SyntaxError: invalid syntax error.

Can anyone help me, please?

Answer 1

For me, this works:

>>> a = rdpcap("test.pcap")
>>> b = a.reverse()
>>> c = a[::-1]

(you can also use the slice notation to create a reversed copy of the list)
