I want to change a variable using another variable without doing the boring old way of:

```
if choice == 'tuna':
  tuna_num -= 1

```

Instead I wanted to do it in a just as quick way as the method seen below:

```
tuna_num = 1
bacon_num = 1

#important bits v
choice = input('Choose a variable name to edit')
(choice)_num -= 1
print((choice)_num)

```

(Sorry if this is simple or if I'm just being stupid)
