Get correct value between 3 values based on language

Question

I have a fairly simple question but yet I don't know what the best and shortest solution to my problem is.

Just for example, I have these variables, name_nl, name_fr and name_en.

Based on language priority (en, nl, fr) I'd like to end up with only one field that I will put in my API.

So if name_en is empty, it should give me name_nl and if that one is empty aswell it should give me name_fr.

So for example:
name_en = ''
name_nl = 'België'
name_fr = 'Belgique'

Desired outcome --> België

name_en = ''
name_nl = ''
name_fr = Belgique

Desired outcome --> Belgique

As a python rookie, I would just work with if statements, but because there are a lot more fields then just "name", I don't wan't to write a massive amount of code.

any tips?

Answer 1

Without knowing the full structure of the OP's code this may or may not be useful.

name_en = '' 
name_nl = 'België'
name_fr = 'Belgique'

print(name_en or name_nl or name_fr)

name_en = '' 
name_nl = ''
name_fr = 'Belgique'

print(name_en or name_nl or name_fr)

Output:

België
Belgique

Answer 2

use something like

def get_next(values):
    next(s for s in values if s)

print(get_next([name_en, name_nl, name_fr]))

Answer 3

That's how I'd suggest to solve the issue, with some changes based on specific needs:

class Word:
    langPriority = ['en', 'nl', 'fr']
    def __init__(self, **kwargs):
        self.translations = kwargs
    
    @property
    def get(self):
        for lang in self.langPriority:
            try:
                if tr := self.translations[lang]:
                    return tr
            except KeyError:
                continue

name = Word(en = '', nl = 'België', fr = 'Belgique')

print(name.get)
