Dear Python.org, 

I'm in a bit of an overwhelmed situation right now, 
so I did not know whom to ask. 

So, I was direct & attached my .py program. 

Why does my variable 
coordinates 
get destroyed along with 
coord 
when I remove elements from it? 
It shouldn't. 
Only coord should get destroyed. 

A family member who is an expert programmer tells me I need to make a 
deepcopy 
of coordinates. 

But, I see absolutely no mention of the word 
deepcopy 
in either your tutorial or PDF of references. I did a word/phrase search for 
deepcopy 
and 
shallow copy. 

Only passing mention was made of 
shallow copy 
on page 9 of your tutorial. 

Please help! 
Thanks, 
John 

P.S. I absolutely need formal structured schooling to learn any language: 
human or computer. This trying to learn it on my own stuff has never worked, 
because I spend days, weeks, months , years searching & searching 
for the right statement. 

I got As in Fortran (1981), C++ (2005) & even passed an online Java course (2012) 
but I never made use of programming outside formal courses.
