Passing argument from one python script to another

I've got 3 files in total : clean.txt, origin.py and pump.py

Clean.txt has some lines in it (actually website links. For eg:

www.link1.com
www.link2.com
www.link3.com
www.link4.com

origin.py is the script that's reading lines one by one and I want this script to send the link (one at a time) to pump.py

pump.py is a script which asks me for one input, which is a link.

Now, I want to make it so that I read lines from clean.txt (origin.py is doing this task) and send them to the pump.py one at a time. Like a loop. Code for Origin.py is :

fo = open("Clean.txt", "r")
nremoval = str(fo.readlines()).replace('\\n','')
      for lines in fo :
          if __name__ =="__main__":
             response = nremoval
             p = subprocess.Popen("pump.py", stdin = subprocess.PIPE)
             time.sleep(2) 
             p.stdin.write(bytes(response, 'ascii'))
             print("injected string :", response)

origin.py

import subprocess
import time

# open file 
with open("Clean.txt", "r") as fo:

     # read line by line
     for line in fo:

         # remove ENTER and SPACES from single line 
         line = line.strip() 

         # call "python pump.py" 
         p = subprocess.Popen(["python","pump.py"], stdin=subprocess.PIPE)

         # or "python3 pump.py"
         #p = subprocess.Popen(["python3","pump.py"], stdin=subprocess.PIPE)

         #time.sleep(2) 

         # send line to standard input
         #p.stdin.write(bytes(line, 'ascii')) # python 3
         p.stdin.write(line) # python 2

         print("injected string:", line)

pump.py

#line = input() # python 3
line = raw_input() # python 2

print("received:", line)
