Hi,
If I use load_module for loading module, I can instantiate classes, defined in
that module. Is it possible to do the same, if load not a module, but package?
Python documentation for load_module contains description, that load_module can

I know the problem is with the for loop but don't know how to fix. Any help
with explanation would be appreciated.

Also common, but how do you specify a keyword, then? Say you have a
command with subcommands:
$0 foo x y
Move the foo to (x,y)
$0 bar x y z
Go to bar X, order a Y, and Z it [eg 'compress',

Better design is to make the argument list a parameter to the ‘main’

I have an ethernet-rs232 adapter which allows me to connect to a measurement
instrument by means of netcat on a linux system.
e.g. entering nc 10.128.59.63 7000
allows me to enter e.g.
*IDN?
after which I get an identification string of the measurement instrument back.
I thought I could accomplish
Long ago, I saw a C program that took another C program as input. It would
output a copy of the original C program, interspersed with fprintf's that
would display the text of the line current being executed.
You might write something similar for Python, perhaps outputting the line
being executed

I have some code which produces a list from an iterable using at least
one temporary list, using a Decorate-Sort-Undecorate idiom. The algorithm
looks something like this (simplified):
table = sorted([(x, i) for i,x in enumerate(iterable)])
table = [i for x,i in table]
The problem here is that

+1 for docopt. It makes everything very clear. Just type out your usage
string, and then run docopt(usage_str) on it to get a dict of your args.
