Ok, if I understand you correctly you want to:
- pass an argument to another script
- retrieve an output from another script to original caller
I’ll recommend using subprocess module. Easiest way would be to use check_output() function.
Run command with arguments and return its output as a byte string.
Sample solution:
script1.py
import sys
import subprocess
s2_out = subprocess.check_output([sys.executable, "script2.py", "34"])
print s2_out
script2.py:
import sys
def main(arg):
print("Hello World"+arg)
if __name__ == "__main__":
main(sys.argv[1])
