error "IndentationError: expected an indented block"

[axa]

Hi
Can you help me to correct the following code so that I do not get IndentationError error?

my script:

You have a function and the body of the function should be indented. you have several if blocks that require indented block after that. in all occasions next line is not indented. Also you have else part that not match any of the preceding ifs. Also first if is indented, when it should not be. Overall your indentation is totally wrong

[ibreeden]

The if statement should be unindented and the lines belonging to the if statement must be indented. The same goes for loops.

1 2 3 4 5 6 7 8 9

if pkt.haslayer(DNSQR):     print('Packet with DNSQR layer found.') if pkt[DNS].qd.qtype == 1:     print('DNSQR type appears type = A') if 'dns' in pkt[DNS].qd.qname and 'msftncsi' in pkt[DNS].qd.qname:     #MUST RETURN TRUE VALUE!        print('It appears captured DNS request requests dns.msftncsi.com')   ... et cetera

Thank you dear friends
I corrected the indented cases
But I still get the error

line 43
else :
^
SyntaxError: invalid syntax

I would really appreciate if you could help me modify this code

To which if does the else on line 43 belong? Probably to the if in line 27. But this if ends on line 30 because "spoofed_pkt" is not indented anymore. So this else belongs to nothing.
