So I want to add the term to the Dict if the term is not yet present in that particular Dict. So if Dict = {}
, and I do Dict.update({'hi':'hello'})
, the Dict would have the ' hi
' as the key. Now say that I have multiple Dicts, such as Dict
, Dict1
, Dict2
... and so on. And now I want to make it so when I want to add this key:value pair into the Dict, if Dict has it, then it will go automatically to Dict1
, and if Dict1
has it, then to Dict2
and so on.
Right now I am stuck on using if [key] in Dict
, then like add it to another, but that doesn't seem to work.
You can put your dicts inside a list then check if the key in the first dict to move the next one, for example:
# some dicts
dict1 = {'cats': 1, 'dogs': 2, 'fish': 3}
dict2 = {'cow': 4}
dict3 = {}
# add the dicts inside a list
dicts = [dict1, dict2 dict3]
# assume I want to add {'dogs': 2} to my dicts
key = 'dogs'
value = 2
# iterate overall dicts inorder to find a dict doesn't contain the key
for dict in dicts:
# this will skip all dicts that contains the key
# so it automatically will go to the next dict
if key not in dict:
dict.update({key: value})
# stop updating after finding the next dict
break
