Question

Hello I'm working on my first python script and I've got a

Syntax Error: if len(sys.argv) =! 5::

I really have no clue what is causing it. I'm using Python v3.3.3 in Wing IDE 5.0 on a windows box. It's my first script but I do know other programming languages so I don't care if the answer is difficult to understand. It's probably a noobish error.. Does it maybe have something to do with the new syntax?

import shodan
import requests
import sys 

SHODAN_API_KEY = "ENTER API KEY IN HERE"
api = shodan.Shodan(SHODAN_API_KEY)
iptotal = ('IP list')
pagenmbr = 1
if __name__ == "__main__":
        if len(sys.argv) =! 5:
                print('Usage: <query> <username> <password> <lastpagenumber')
                sys.exit(0)

                query = sys.argv[1]
                username = sys.argv[2]
                password = sys.argv[3]
                endpage = sys.argv[4]
                iteratePage(pagenmbr)



                def iteratePage(pagenmbr):
                        try:
                               ...

                        except (shodan.APIError, e):
                                print ('Error: %s' % e)  

pagenmbr = pagenmbr + 1

if pagenmbr <= endpage:
        iteratePage(pagenmbr)

print(iptotal)
#Append succeeded items to file
with open("outputsbb.txt", "a") as myfile:
        myfile.write(iptotal)

I left out the try commands to save some space. If anybody has had this error before or could help me with this plz reply and help a fellow coder out it's really appreciated

Solution

You invert the ! and the = in your condition. You wanted to write:

if len(sys.argv) != 5:
     #...

See list of Python operators

OTHER TIPS

You want len(sys.argv) != 5

  • != is "is not equal to"
  • =! does not exist in the python grammer
