Hi David,
Thanks for your input about the logic of this little script of mine.
I confess I omitted the edge possibility and assumed heads or taisl only.
As I progress further with getting the foundation knowledge of the language
itself, it is really appreciated to be corrected on what good programming is
about regardless of the language.
Please keep commenting/helping whenever necessary.
Cheers,
Marc

Here is a problem I've come across, from empirical evidence, that also relates
to your equation. We always assume
that their are always two probabilities, that a coin can be either head or
tails.
However, there are dynamics within a third realm of the dimensionality of the
coin...it's not a two dimensional plane. So the planar probabilities in
relation to the 'surface are' hold another possibility...the 'edge'.
The algorithm of applying the edge are up to you, but I've seen the coin land
on it's curved edge more than once, so this function you've designed, should
have more than two possibilities, within a complete algorithm to the real world
functionality of the coin in question.

Hello there,
I want to emulate a coin flip and count how many heads and tails when flipping
it a hundred times.
I first coded coinflip_WRONG.py with "count_flips += 1" statement within the
if/else block.
When running it, either returned values are wrong or the script seems to enter
in an infinite loop showing no return values at all.
coinflip.py is a corrected version I worked out myself. I moved "count_flips+=
1" out of if/else block and inserted it before if/else.
However, I still don't understand the bug since, in my understanding, both
files are incrementing variable count_flips each time until the loop becomes
false.
Can somebody explain the reason of the bug.
Cheers,
Marc
