Dear Pythoners,
I have written a python application which authenticates a user, reads a
webpage and searches for pattern and builds a database ( In my case its a
dictinary with fixed set of keys).
Inputting the username and password for authentication and final display of
the results is done by GUI
That's really easy:
>>> import re
>>> reload(re)
>>>
In python2.x, but if you are using python3.x I think is different, really
easy to know if you search in python docs.

You can run "ps --ppid " and get the line containing test program.
The first field there should be the child process id.

"x=42" is an assignment statement, not an expression.
In "bool(x=5)", "x=5" is also not an expression. It's passing the
expression "5" in as the parameter x,

Python and Java have overall very different performance profiles, but
