Replace imported list of constants with another list in Python

Question

My GUI application has two radiobuttons for changing the displayed language. The words are assigned to the constants text1, text2, an so on, in two files:
file_en.py:

text1 = 'Hello'  
text2 = 'Goodbye'  
...  

file_fr.py:

text1 = 'Bonjour'  
text2 = 'Au revoir'  
...  

On start, the main module imports file_en or file_fr and everything is fine. Now, when the user changes the language - can I immediately replace one imported constants assignment with another?

Answer 1

I don't think that is possible, but I think I found a workaround for that. How about you have a function ( loadLang() or something) that will change the language each time it is called, reading 2 different text files.

text1=''
text2='' 
activeLang = 'en' #current language

def loadLang(lang):
    global text1
    global text2
    global activeLang
    if activeLang != lang: #check if current language is 
already what user wants
        file=open("file_" + lang + ".txt", "r") #open file 
       #assuming contents are same as your post without  spaces
        text1=file.readline().rstrip()
        text2=file.readline(2).rstrip() #read line and remove 
\n
       return

#main code
#idk how you're doing it so:
def onClick():
global text1
global text2
       if 'fr' in button.text:
           loadLang('fr')
button1.text = text1
button2.text = text2

Updated solution

You should try this instead, it's must more simple and efficient.

import file_en
import file_fr
text1=""
text2=""
activeLang = 'en'#current language
def onClick():
    global text1
    global text2
    global activeLang
    if activeLang == 'en':
        text1 = file_fr.text1
        text2 = file_fr.text2
    elif activeLang == 'fr': #check lang
        text1 = file_en.text1
        text2 = file_en.text2
     else:
        # Error handling goes here
