I can't see what is triggering the invalid Syntax error

I am currently trying to replicate a packet sniffer in python that can parse udp, tcp, and ICPM packets.
As it is now no other compiler errors show except an invalid syntax error.
#packet sniffer for linux in python
import socket, sys
from struct import*
#A function that converts a string of 6 characters of ethernet address into dash seperated hex string
def ethernet_address (string):
new_String = "%.2x:%.2x:%.2x:%.2x:%.2x:%.2x" % (ord(string(0)), ord(string(1)), ord(string(2)), ord(string(3)), ord(string(4)), ord(string(5)))
return new_String
#Section that creates the socket
try:
sock = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.ntohs(0x0003))
except socket.error as msg:
print ("Socket could not be created, Error : ")
print (msg)
sys.exit()
#recieve a packet
while True:
packet = sock.recvfrom(60000)
#packet string from tuple
packet = packet[0]
#parse ethernet header
ether_length = 14
ether_Header = packet[:ether_length]
ether = unpack('!6s6sh', ether_Header)
ether_protocol = socket.ntohs(ether[2])
print ("Destination MAC: " + ethernet_address(packet[0:6]) + "Source MAC: " + ethernet_address(packet[6:12]) + " Protocol: " + str(ether_protocol))
#This section handles parsing IP packets
if ether_protocol == 8:
#Parse the IP header
#take the first 20 character from the header
ip_header = packet[ether_length:20 + ether_length]
#now unpack
iph = unpack('!BBHHHBBH4s4s', ip_header)
version_ihl = iph[0]
version = version_ihl >> 4
ihl = version_ihl & 0xf
iph_length = ihl * 4
ttl = iph[5]
protocol = iph[6]
source_address = socket.inet_ntoa( iph[8] )
destination_address = socket.inet_ntoa( iph[9] )
print("Version: " + str(version) + " IP header length: " + str(ihl) + " TTL: " + str(ttl) + " Protocol: " + str(protocol + " Source Address: " + str(source_address) + " Destination Address: " + str(destination_address) )

h_size = ether_length + iph_length + tcph_length * 4
data_size = len(packet) - h_size
#get data
data = packet[h_size:]
print ("Data: "+ data)
#This section Handles parsing ICMP packets
elif protocol == 1:
u = iph_length + ether_length

icmp_type = icmph[0]
code = icmph[1]
checksum = icmph[2]
print("Type: " + str(icmp_type) + " Code: " + str(code) + " Checksum: " + str(checksum))
h_size = ether_length + iph_length + icmph_length
data_size = len(packet) - h_size
#retrive data
data = packet[h_size]
print("Data: " + data)
#This section handles parsing UDP
elif protocol == 17:
u = iph_length +ether_length
udph_length = 8
udp_header = packet[u:u+8]
#now unpack them
udph = unpack('!HHHH', udp_header)
src_port = udph[0]
dest_port = udph[1]
length = udph[2]

print("Source Port: " + str(src_port) + " Destination Port: " + str(dest_port) + " Length: " + str(length) + " Checksum: " + str(checksum) )

data_size = len(packet) - h_size
#get data
data = packet[h_size]
print("Data: " + data)
else:
print("Protocol is something other than UDP, ICMP, or TCP")
print
The error is caused by the line:
if protocol == 6 :
Visual Studio says that this is a syntax error, but I'm of how because it is written just like every other if statement and they don't have a syntax error warning. What is the error if there is one?

I believe you are missing a bracket. print("Version: " + str(version) + " IP header length: " + str(ihl) + " TTL: " + str(ttl) + " Protocol: " + str(protocol + " Source Address: " + str(source_address) + " Destination Address: " + str(destination_address) )) should work.
Note: I added a bracket at the end but that might not be where it should be added for your code to function as intended despite removing the error. It seems print("Version: " + str(version) + " IP header length: " + str(ihl) + " TTL: " + str(ttl) + " Protocol: " + str(protocol) + " Source Address: " + str(source_address) + " Destination Address: " + str(destination_address) ) is likely what you want.

The error is found in the line above:
print("Version: " + str(version) + " IP header length: " + str(ihl) + " TTL: " + str(ttl) + " Protocol: " + str(protocol + " Source Address: " + str(source_address) + " Destination Address: " + str(destination_address) )
Specifically, the error comes from ... str(protocol + ..., which should be ... str(protocol) + ....

You have an unmatched parenthesis on the previous line:
print("Version: " +
str(version) +
" IP header length: " +
str(ihl) +
" TTL: " +
str(ttl) +
" Protocol: " +
str(protocol +
" Source Address: " +
str(source_address) +
" Destination Address: " +
str(destination_address)
)
You probably want something like this:
print("Version: " +
str(version) +
" IP header length: " +
str(ihl) +
" TTL: " +
str(ttl) +
" Protocol: " +
str(protocol) +
" Source Address: " +
str(source_address) +
" Destination Address: " +
str(destination_address)
)
Also, consider using " ".join(iterable) to join strS with spaces. Concatenation is inefficient (not an issue here) and difficult to read (definitely an issue here).

A multi-input PySimpleGUI for a working python script

I'm using a working script built in python 3 that reads an excel file. Using the input, it figures out which VIP (Virtual IP) subnet I should use and which F5 load balancer the VIP should be matched with, and then spits out the cli commands needed to configure on the load balancer as another file. I want to know if it's possible to add a basic GUI to this using the code I have below. Based on that, it will create a file on my desktop with the commands I need to configure taken from the excel file and input given. If the information is blank within excel it will prompt and ask you. An edited example of a simple working script that runs is shown below:

It was suggested to me to put the script as a function and import it to the code for the GUI which I did and named it vipTest. Next I imported it to PySimpleGUI I am using to create a simple form with here:
import vipTest
import PySimpleGUI as sg
# Very basic form. Return values as a list
form = sg.FlexForm('VIP Builder') # begin with a blank form
layout = [
[sg.Text('Please enter the information below')],
[sg.Text('What is the change order for this VIP?: ', size=(30, 1)), sg.InputText('change #')],
[sg.Text('Enter the full path of the LBARF form: ', size=(30, 1)), sg.InputText('location path')],
[sg.Text('Which VIP IP did you choose?: ', size=(30, 1)), sg.InputText('ip address of vip')],
[sg.Submit(), sg.Cancel()]
]
lbarf_file, folder = vipTest.createfolder(directory)
button, values = form.Layout(layout).Read()
I am having trouble getting an output from the GUI of the results. When I run this program in PyCharm the GUI does not open and script runs in the console. Even if I can get the GUI to work with a specific example, I am concerned I might need to have the GUI add a text field each time the information in the excel file is blank. I would like to ultimately like to display the config commands from the gui but am not getting anywhere with it as is. Any assistance on this is greatly appreciated. Thank you.

Inserting new ips into a list

I have this program that list ip addresses on my network and if they are online or offline along with the mac address. i want the offline ips to be in a list so that i can check if that ip is not in the list it will it will display NEW.
idk what to do

OKBLUE = '\033[94m'
OKGREEN = '\033[92m'

maxr = int(input("Ending Ip: "))
ofip = ["192.168.2.0"]
while True:
for num in range(minr, maxr + 1): #plus one is to include the last digit entered
ip = "192.168.2." + str(num)
from getmac import getmac
exit_code = os.system("ping -n 1 -w 1 " + ip + " > nul") # Windows
getmac.PORT = 44444 # Default: 55555
if exit_code == 0:
print(ip, bcolors.OKGREEN + "ONLINE " + bcolors.ENDC + bcolors.OKBLUE + get_mac_address(ip=ip, network_request=True) + bcolors.ENDC)
elif exit_code != 0:
print(ip, bcolors.FAIL + "OFFLINE" + bcolors.ENDC)
ip = ofip
elif exit_code != 0 and ip != ofip:
print(ip, bcolors.OKGREEN + "NEW " + bcolors.ENDC + bcolors.OKBLUE + get_mac_address(ip=ip, network_request=True) + bcolors.ENDC)
else:
print(ip, bcolors.FAIL + "OFFLINE" + bcolors.ENDC)
i should see offline ip address that goes online print new

This line will not do what you are intending. You need to make a few changes.
elif exit_code != 0 and ip != ofip:
ofip is a list (at least it is at first) and ip is a string, != will not work here. You should be using the in operator.
elif exit_code != 0 and ip not in ofip:
Second issue is addressing that ip is a string and ofip is a list (when you first assign it, later you set it to a string).
Instead of doing,
ip = ofip
try appending to the list
ofip.append(ip)
Last thing is that is that because of how your if/elif statements flow, the second elif will never run.
If the exit code is not 0 then it will always hit the first elif and will never hit the second one. Switch these. Put your more specific conditionals before your less specific ones.
Tip: you can use a set instead of a list for faster lookups.

It seems that the file reads fine and the socket creates, but it only connects to one server then it gives the error.

You can't re-connect a socket. Once it's connected, it's connected. Even if you call close:
all future operations on the socket object will fail.
The right answer is to create a new socket each time through the loop, whether with create_connection or with socket and connect. For example, change your try block to this:
try:
sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM);
sock.settimeout(3);
sock.connect((ip,port));
print Colors.cyan + ip + ":" + str(port) + Colors.none + " is " + Colors.green + "UP";
sock.close();
except socket.timeout:
print Colors.cyan + ip + Colors.yellow + ":" + Colors.cyan + str(port) + Colors.none + " is " + Colors.red + "DOWN";

print the result of a scapy function in tkinter

a=lb + "(IP(src='" + SrcIP + "', dst='" + DestIP + "')/TCP(sport=" + SrcPort + ", dport=" + DestPort + ",flags='"+P+""+S+""+A+""+U+""+F+""+R+"'), timeout=" + Timeout + ")"
p=eval(a)
p.show()
tkMessageBox.showinfo(title = "the configuration and results", message = "The configuration is:\nFlags:"+psh+"\n"+syn+"\n"+ack+"\n"+urg+"\n"+fin+"\n"+rst+"\nSource IP:"+SrcIP + "\nDestination IP: " + DestIP + "\nSource Port: " +SrcPort+ "\nDestination port: " + DestPort + "\nTimeout: " +Timeout+"\nSend/Received method: "+lb+"\t")
How can i put the result of p.show() in tkMessageBox.showinfo?

I don't think you can, as the .show() method only uses print statements.
