Before causing us to sharpen our knives (the Ides of March has passed!), 
please copy-paste your code and any error messages (Tracebacks), ie 
straight from the terminal window into the email msg.

There are a number of inconsistencies in the code-presented, and it is 
confused by in-line comments which are not preceded by #

eg "Belt Counter ==  Counter({'40885': 9, '37869': 3, '46041': 1})" is 
not legal Python and requires the collections library be imported (I assume)

add to the above line of 'code':

c = belt_dict
dict(c)
print('Uses belt_dict Counter ')

and the multiple terms (for what I assume is the same collection of 
values) becomes confusing to simple-minds (like mine).

The "dict(c)" is unused (and unusable).

Right, now that I've grumped (more than) enough:

Please take a look at the keys and values in 
"parts_in_inv_dict"/"inv_dict". What data-type(s) are they - are these 
(both) integers, strings, floats, booleans, ...or what?

Similarly, inspect "Belt Counter"/"c"/"belt_dict". What data-types are 
used here?

Spotted the difference?

NB in Python: 40885 != '40885'
