Execute a file with arguments in Python shell

Question

I would like to run a command in Python Shell to execute a file with an argument   For example  execfile  abc py   but how to add 2 arguments

execfile runs a Python file  but by loading it  not as a script  You can only pass in variable bindings  not arguments  If you want to run a program from within Python  use subprocess call  E g  import subprocess subprocess call     abc py   arg1  arg2

try this   import sys sys argv     arg1    arg2   execfile  abc py     Note that when abc py finishes  control will be returned to the calling program   Note too that abc py can call quit   if indeed finished

If you set PYTHONINSPECT in the python file you want to execute   repl py   import os import sys from time import time  os environ  PYTHONINSPECT      True  t time   argv sys argv 1 len sys argv     there is no need to use execfile  and you can directly run the file with arguments as usual in the shell   python repl py one two 3  gt  gt  gt  t 1513989378 880822  gt  gt  gt  argv   one    two    3

For more interesting scenarios  you could also look at the runpy module  Since python 2 7  it has the run path function  E g   import runpy import sys    argv 0  will be replaced by runpy   You could also skip this if you get sys argv populated   via other means sys argv         arg1   arg2   runpy run path    abc py   run name    main

You re confusing loading a module into the current interpreter process and calling a Python script externally    The former can be done by importing the file you re interested in  execfile is similar to importing but it simply evaluates the file rather than creates a module out of it  Similar to  sourcing  in a shell script    The latter can be done using the subprocess module  You spawn off another instance of the interpreter and pass whatever parameters you want to that  This is similar to shelling out in a shell script using backticks

Besides subprocess call  you can also use subprocess Popen  Like the following  subprocess Popen     script   arg1  arg2

If you want to run the scripts in parallel and give them different arguments you can do like below    import os os system  python script py arg1 arg2  amp  python script py arg11 arg22

You can t pass command line arguments with execfile    Look at subprocess instead
