Often, when I am developing code, I get an error message saying that
"IDLE's subprocess can't make connection"
Sometimes this happends when I have IDLE open, and am about to hit F5
to run a program-in-process.

I have a number-to-Roman numeral program that churns out ValueError
messages with a few improper input cases:
1. not an integer
2. larger than 3999
3. smaller than 0
When I run the program via IDLE, and I give one of these improper
inputs, the interpreter closes down the program and then disp
I have a program producing a list of multiple strings.
The amount of strings in the list varies.
I want to assemble a string that is:
list item 0 + space + list item 1 + space,
and so on, going through every string in the list.

Given a string, how would I?:
1. Make sure only the first letter string_name[0], is capitalized.
This would involve using string_name.lower() to lowercase everything
else, but how do I use .upper(), or some other method, to capitalize
only the first character?
2. Make sure that there are no s
My programs often have long, detailed loops in them, and would like
to, as I'm executing the loop, view what part of the loop Python is
currently processing.
Thus, if my program gets stuck in one part of the loop, I would see that.

How do you 'tell' Python to repeat a certain action X amount of times,
and then stop.
I could use a 'counter' (see below), but that seems kind of clunky.
counter = 0
example = True
while example:
print "Do something"
counter += 1
if counter == 100:
example = False

What is the best (only?) way to set up an array in Python.
I've heard they can be quite good for certain types of data you need
to organize...
What IS the best reason(s) to be using an array?
Apologies, if Python has something similar by a different name.
Ah, a simple concept. Good. :)
I'm already familiar in working with lists.
Here's a case of a simple two-dimensional array (the simplest
possible), ran in the IDLE interpreter:
>>> array = [["1.1", "1.2"], ["2.1", "2.2"]]
>>> array[1[2]]
Traceback (most recent call last):
File "", line 1, i
Why Python starts counting at [0] instead of at [1] is a whole other issue. :D
array = [["0.0", "0.1"], ["1.0", "1.1"]]
array[0[1]] seems right, although it isn't, because the index (0) and
the subindex(1) are nested in 'array[0[1]]' much like the list and
sublist that I'm "calling" from with

Yeah, that's what the wiki-based tutorial mentioned.
In fact, Lee Harr (my community adviser) also suggested using a random number.

Hello All.
I've been concocting some simple programs based on an online tutorial,
and I, of course, save a program as a .py file.
When running my program via IDLE, once I've cleaned out the bugs, it
works as I expect it to.
But I noticed something else:

Hey! Glad to hear that using raw_input() at the end is the actual
solution, not just a jury-rigged workaround. :)
So sleep(10) would simply be a shorter snippet of code for that purpose?
The \n thing might be handy if I was short on space, but I don't mind

This, I heard, is more difficult than digital-to-Roman, since you have
to "read" the subtractive cases, with a smaller numeral placed before
a larger numeral, without simply adding all the numerals' values up

numeral he/she want

Roman Numeral - To - Digital Converter
So far, I'm coming along OK with the code that runs the conversions,
assuming the user gives me a proper input. (A string of capital
letters I, V, X, L, C, D, M)
However, not every input someone gives the function is goign to be
properly formatted like
#start of triple-letter processing block
if len(roman_input) > 2 and roman_input[0] + roman_input[1] +
roman_input[2] == "MMM":
digital_result += 3000
roman_input = #something to remove those "M"'s from the string

Is there a way in Python to separate a string into its component words.
