Question

I’ve got a few lines of code for iterating over a dict within a list and I’m looking to shorten it. It works perfectly as is, but seems like too much code and I’m trying to get a feel for how to keep code efficient in Python (or in general really).

for d in dev['devices']:
    if d['name'] == devName:
        devFound = True
        break

The structure of ‘dev’ is a bit confusing but for the data I care about:
dev (dict) > devices (list) > 0-n (dict)

the value ‘name’ is a key within the inner numbered dict (varies depending on the search value elsewhere) which needs to be checked against a user input (devName)

Any input much appreciated

Answer 1

Basically the same, only rewritten with some built-in function and a generator:

devFound = any(d['name'] == devName for d in dev['devices'])
