Get values for batch of keys without loop in python

Question

I'm building dictionary in python from a table which is ~2Gb big. It includes ID and description. eg:

id	description
COG5157	cell division cycle 73
COG5153	Lipase
COG5156	complex subunit 10
COG5151	Transcription factor

and I also have another file with IDs, which I would like to map on this table (to obtain description) I have approximately 140000 IDs

I'm running it in python3 for loop, which is actually pretty slow (up to 90 minutes).

nogidsdict=nog_db.set_index('id')['description'].to_dict()
prof_db['description']=""
for i in range(len(prof_id)):
    try:
        prof_db.iloc[i,2]=nogidsdict[prof_id[i]]
    except:
        prof_db.iloc[i,2]='None'

Is it possible to obtain values from dictionary for batch of keys without looping? Do you have any suggestion how I could speed up this part of script?

Thank you in advance!
