Output - with and without spacing

Python - Fundamentals example from a Well House Consultants training course
More on Python - Fundamentals [link]

This example is described in the following article(s):
• Python - fresh examples from recent courses - [link]

Source code: leadollar Module: Y102

""" If you output a single expression with 'print', the expression will
be evaluated and printed to STDOUT, and a new line will be appended. If
you add a trailing comma (Python 2), then the new line will be replaced
by a space.

With several, comma separated, expressions in a print call, Python 2 will
output each of the expressions and will separate them with a space ... and
it will still add a new line, or space, on the end depedning on whether there
isn't or is a trailing comma.

QUESTION ... how do you avoid getting the space between each parameter?

ANSWER ... combine the parameters into a single parameter - and the easiest
way to do this is to treat each of them as a string and use "+" to
concatenate them. Here's an example where we want a $ symbol in front
of an amount, and we want to supress the space:

NOTE - this also makes the output Python2 and Python 3 compatible! """

amount = 16

print("That will cost $",amount,"each")
print("That will cost $" + str(amount) + " each")

""" Sample Output

WomanWithCat:y102 grahamellis$ python2 leadollar
('That will cost $', 16, 'each')
That will cost $16 each
WomanWithCat:y102 grahamellis$ python3 leadollar
That will cost $ 16 each
That will cost $16 each
WomanWithCat:y102 grahamellis$
