Maybe something like this:
moduleA.py:
-----------
def someFunc():
print "hello"
raise ValueError
someFunc()
----------
import subprocess
print "Main executing"
try:
p = subprocess.Popen(["python", "6test.py"],
stdout=subprocess.PIPE,
stderr=subprocess.PIPE)
result = p.wait()
if result == 0:
print "output:", p.stdout.read()
else:
print "output before error:", p.stdout.read()
print "error:", p.stderr.read()
except (OSError, TypeError, ValueError), e:
print "subprocess was never started"
print e
