Why don't you try it for yourself and find out? At the inte

Hi Robert,
As Lukas mentions, it sounds like you're looking for a "flag parsing"
library. A flag parsing library reads a set of key/value pairs that are
encoded in sys.argv, so they let comman
NO, NO, NO. The OP is using Python 3.4, and has consistently
shown results accordingly. x does NOT exist after the list
comprehension. That was a flaw in python 2.x which has been
fixed.
Sorry about that, all. I still use Python 2.x most of the time, so
defaulted to that. I am glad that
Hello,
take a look at argparse library.

import argparse
parser = argparse.ArgumentParser(description="My prgoram")
parser.add_argument('-y', '--y', help="Y value", required=True)
parser.add_argument('-x', '--x', help="X value", required=True)
def main(x=1, y=2):
print x

I have a function with optional arguments x, y and I would like to pass y
or z using a named variable through the command line. Inside a python
script main(y=3) would work, but I have trouble passing y=3 as an argument
in command line.
I have tried the following:
import sys
def main(x=1, y=

Hi there Clayton,
values = [ ('a', 1), ('b', 2), ('a', 5), ('c', 7)]
key = 'a'
pair=[] # -- this assignment is unnecessary
x=[pair for pair in values if key == pair[0]]
print(x)
I get [('a', 1), ('a', 5)]
I also get that result. Good.
So, what does that first pair do? I see and have
