How to localize an application?

Question

Python

Depending on the settings, it is necessary to output a string in different languages ​​(English/Ukrainian/Russian). I asked my friends and drew 2 options:

1. Use a file .pywith constants. for exampletranslation.EN_CREATE_BUTTON
   
2. Use the configparser library and take a line from there. for exampletranslation["EN"]["create_button"]
   

Maybe there are other options? We need the opinion of knowledgeable people
upd. You still need to format the strings somehow. for exampleDelete {user} account
