Python dict - some keys with the same value-CodePudding

I'm trying to do a dictionary which include countries GMT time (int number) for example I have a dict and I want to get the value of it, I tried this code:

countires= {('Jerusalem', 'Athens', 'Bucharest'):2 ,('Bahrain','Qatar'):3}
print(countires.get('Athens'))

and the output is:

None

How I can get result 2?

IIUC, You need create temp dict that have seperate key and search what you want like below:

>>> countires= {('Jerusalem', 'Athens', 'Bucharest'):2 ,('Bahrain','Qatar'):3}

>>> dct = {k:value for key,value in countires.items() for k in key}

>>> print(dct.get('Athens'))
2

If you want to use your original dictionary you can define function and search in keys like below:

>>> def search_multi_key(search, dct):
...    for key, value in dct.items():
...        if search in key:
...            return value
...    return None
        
>>> search_multi_key('Athens', countires)
2

One approach is to create a new dictionary, that uses as key each of the elements of the tuples:

countries= {('Jerusalem', 'Athens', 'Bucharest'):2 , ('Bahrain', 'Qatar'):3}
cities = { key : value for keys, value in countries.items() for key in keys }
print(cities.get('Athens'))

Output
