Call same python script in for loop from another python script

Question

I have a scenario, where I have to call a certain Python script multiple times in another python script.

script1:

import sys

path=sys.argv

print "I am a test"
print "see! I do nothing productive."
print "path:",path[1]

script2:

import subprocess

l=list()
l.append('root')
l.append('root1')
l.append('root2')

for i in l:
    cmd="python script1.py i"
    subprocess.Popen(cmd,shell=True)

Here, my issue is that in script 2, I am not able to replace the value of "i" in the for loop. Can you help with that?

Just create the string in the for loop. cmd = "python script1.py " + str(i). You are hardcoding i as a character, and not using its value. — sparkonhdfs

to substitute the value of i into the string you can concatenate it:

cmd="python script1.py "+i

or format it into the string:

cmd="python script1.py %s"%i

Either way you need to use the variable i instead of the string i.

I think you are looking for this:

cmd="python script1.py %s" % i

Use subprocess.Popen with a lists:

import subprocess

paths = ['root', 'root1', 'root2']

for path in paths:
    subprocess.Popen(['python', 'script1.py', path])
