Multi Language Support In Python Script

I have a large python (2.7) script that reads data from a database and generate pictures in pdf format. My pictures have strings for labels, etc... Now I want to add a multi langu

Solution 1:

see python gettext module for i18n support

Solution 2:

If you only have a few languages, and don't want to use some i18n stuff, try one of these:

example (I'm just using a dict in a py file, let me know if you want specifically json):

also, this is written in python 3, not 2.

in en.py

en = {
    "eng": "english",
    "heb": "hebrew",
    "menu": {
        "menu1": "one",
        "menu2": "two"
    }
}

in he.py

he = {
    "eng": "אנגלית",
    "heb": "עברית",
    "menu": {
        "menu1": "אחד",
        "menu2": "שתיים"
    }
}

option 1 using SimpleNamespace:

from types import SimpleNamespace

#import language dicts from which ever folder and file they are, for me its the same folder and different files...from .he import he
from .en import en

classNestedNamespace(SimpleNamespace):
    def__init__(self, dictionary, **kwargs):
        super().__init__(**kwargs)
        for key, value in dictionary.items():
            ifisinstance(value, dict):
                self.__setattr__(key, NestedNamespace(value))
            else:
                self.__setattr__(key, value)

text = {}
text.update({"he": NestedNamespace(he)})
text.update({"en": NestedNamespace(en)})
print(text['he'].menu.menu1) #works

option 2 using namedtuple (i think this one is slower, by what i read about the way namedtuples are made, but im no pro, so choose whatever you like):

from collections import namedtuple

def customDictDecoder(dict1):
    for key, value in dict1.items():
        if type(value) is dict:
            dict1[key] = customDictDecoder(value)
    return namedtuple('X', dict1.keys())(*dict1.values())

text = {}
text.update({"he": customDictDecoder(he)})
text.update({"en": customDictDecoder(en)})
print(text['he'].menu.menu2) #works

if you want print(text.he.menu.menu1) to work, it is possible, but i dont see the use for it, if you want it, let me know

Solution 3:

I had this problem a while ago and just solved it by creating two arrays with the words of the two languages I needed.

# array with english wordsengList = ["dog", "cat"]
# array with german wordsgerList = ["Hund", "Katze"]

Then I just set another array to the needed language array and use the words from this array.

# referenced array set to the english array
langList = engList

print(langList[0],"+",langList[1])

# change to the german array when needed
langList = gerList

print(langList[0],"+",langList[1])

Of course it's no way near to be perfect, but it worked for me. Hope I could help!

Solution 4:

A more 'pythonic way' could be if you just make a different .py and make a new class there with if statements for each language:

classLocale:
def__init__(self, loc):
    if loc == "en":
        self.string = "something in English"elif loc == "fr":
        self.string = "something in French"
