set - how to change a variable to a different value without using many if - statements python

Question

Let's say I have a variable called temperature. And I want its value to be different according to the conditions. Normally I would do something like this:

temperature = None
country = input()
if country == 'USA' :
    temperature = 10
elif country == 'Spain':
    temperature = 20
elif country == 'Peru':
    temperature = 30
#and so on

But that takes forever, if I have many values. I have a feeling I need to use sets but I haven't begun using them (and dictionaries). However if that is the way to do it, I'd like to know.

Answer 1

Do you mean something like that?

country = input()
cond = {'USA': 10, 'Spain': 20, 'Peru': 30 } 
temperature = cond.get( country, None )
