Is there a proper method of assigning conditions to the if or elif functions?

Say I have multiple conditions, how should I determine whether or not a condition is the first if or second elif?

it doesn't really matter, you just need to cover all possibilities of whatever you're doing. after an if and a series of 0 or more elifs, you have the else as a default, if no other condition is met.

It only matters if some conditions have a higher priority or if there is some sort of overlap between the conditions.

e.g.

def legal_to_drink(age, country):
    if age >= 21:
        legal = True
    elif age >= 18 and country != 'USA':
        legal = True
    else
        legal = False

    return legal

legal_to_drink(32, 'Australia')  # returns True
legal_to_drink(25, 'USA')  # returns True
legal_to_drink(20, 'USA')  # returns False
legal_to_drink(20, 'UK')  # returns True
legal_to_drink(16, 'UK')  # returns False
