If you must...this will break if there is no match, and it will always
enumerate the entire data list:
[ i for i, d in enumerate(data) if d['id']== id_to_match ][0]
For the readable version, which won't break if the id is missing, and
may be faster depending on the data:
for i, d in enumerate(data):
if d['id'] == id_to_match:
break
else:
i = None # or whatever you want to do to signal no match
Alternately, maybe you should be storing data in a dict indexed by id
instead of in a list?
