I've been working on a program and have had to halt it due a slight problem.
Here's a basic version of the code:
a = 'filled'
b = 'filled'
c = 'empty'
d = 'empty'
e = 'filled'
f = 'empty'
g = 'filled'
testdict = {a : 'apple' , b : 'banana' , c : 'cake' , d : 'damson' , e : 'eggs'
, f : 'fish' , g : 'glue'}
Now what I want to do, is if a variable is filled, print it out. This however
isn't working how I planned. The following doesn't work.
for fillempt in testdict:
if fillempt == 'filled':
print(testdict[fillempt])
All this does though, is print glue, where I'd want it to print:
apple
banana
eggs
glue
Perhaps a dictionary isn't the best way to do this.. I wonder what else I can
do...
Thanks for any help.
You've effectively set up a dictionary with keys 'filled' and 'entries'
which you can see if you run this loop
for key, value in testdict.items():
print(key, value)
which gives me this
empty fish
filled glue
I'm too lazy to type anything else so please refer to this

I'll also leave the argument over whether it's a variable or a name to
others :)
