Question

I tried that, but when I try to print these arguments it returns no values.
I submit my code below:

script1 that runs external python program (script2)

#(...)
proc = subprocess.Popen(['export PYTHONPATH=~/:$PYTHONPATH;' +
    'export environment=/path/to/environment/;' +
    'python /path/to/my/program/myProgram.py',
    '%(date)s' %{'date':date}, '%(time)s' %{'time':time}],
    stdin=PIPE, stdout=PIPE, stderr=PIPE, shell=True)
#(...)

script2 that is being run by the script1

#(...)
print sys.argv[0] #prints the name of the command
print sys.argv[1] #it suppose to print the value of the first argument, but it doesn't
print sys.argv[2] #it suppose to print the value of the second argument, but it doesn't
#(...)

Answer 1

Try this version of script 1:

proc = subprocess.Popen('python /path/to/my/program/myProgram.py %s %s' % (date, time),
                        stdin=PIPE, stdout=PIPE, stderr=PIPE, shell=True,  
                        env = {'PYTHONPATH': '~/:$PYTHONPATH',
                               'environment': '/path/to/environment/'})

It should make it easier to find your problem if it doesn’t work; but I think it will.
