... or am I missing something?
With Python 2.0 on Windows 2000, when playing with sys.exit() and sys.argv()
I get some unexpected results.
First here is a simple case that shows what I expect. I run "caller_good.py"
which call "callee_good.py" and prints its return value. "callee_good.py"
returns 42 so "42" is printed:
----------------- caller_good.py --------------------
import os
retval = os.system("python callee_good.py")
print "caller: the retval is", retval
-----------------------------------------------------
----------------- callee_good.py --------------------
import sys
sys.exit(42)
-----------------------------------------------------
D:\trentm\tmp>python caller_good.py
caller: the retval is 42
Now here is what I didn't expect. I changed "caller_bad.py" to pass, as an
argument, the value that "callee_bad.py" should return.
----------------- caller_bad.py ---------------------
import os
retval = os.system("python callee_bad.py 42")
print "caller: the retval is", retval
-----------------------------------------------------
----------------- callee_bad.py ---------------------
import sys
firstarg = sys.argv[1]
print "callee_bad: firstarg is", firstarg
sys.exit(firstarg)
-----------------------------------------------------
D:\trentm\tmp>python caller_bad.py
callee_bad: firstarg is 42
42 # <---- where did *this* print come from?
caller: the retval is 1 # <---- and this retval is incorrect
Any ideas? I have not tried to track this down yet nor have I tried the
latest Python-CVS state.
