Hej there,
I don't know if everyone would consider this more elegant but it's
certainly shorter:
Thanks!
def DigitSum(YourNumber):
... return sum(map(int, YourNumber))

I don't understand yet what the map function does - can you explain?
I read the Python 3.3.0
Thanks Steve, Alan. Sound advice. Very much a novice so trying to pick up
good habits. Will definitely take on board your comments!
Thanks again.

The map function comes from so-called functional programming

First it calculates the digit sum, and then it prints it.

In Python 2.7, you can abbreviate that last one slightly:

Why 2.7? By me also works with 3.3.
Either should be preferred to building the string by hand with + signs.

Sorry, I meant Python 2.7 or later.

Hej Steven,
thanks for the clarification.
I have two questions - one about map function and the other about return.
So, in mathematics we might have a mapping between (let's say) counting
numbers 1, 2, 3, 4, ... and the even numbers larger than fifty, 52, 54,
56, ... and so on. The mapping

There exists two Linux machines A and B. Machine B contains python script
which needs to be run e.g. Test.py
In order to run that script, machine A needs to telnet into machine B and

How can this be implemented? Is subprocess library to be used?if yes, an

Hi,
Ok; so in your situation, it sounds like machine A is also running a
Python script, and you want to automate the remote administration of
machine B through that program. If that's the case, you may want to
look at the Fabric library, or other libraries that help with
driving ssh through Python:
