Adding a constant integer to a value in a python dictionary

Question

How would you add a constant number, say 1, to a value in a dictionary if certain conditions are fulfilled.

For example, if I had a dictionary:

dict          


        

Answer 1

Your code says the following:

for each value in [3,3,4,4,4]:
    if 1 < value < 5:
        FID_thingy['0'] = value + 1

So it will set FID_thingy['0'] to 4 then 4 then 5 then 5 then 5. Do you see why?
