how to translate the texts with python?

I'm trying to find a way to translate some texts with else if but I can't find the way to do it:
What I try to translate is the following part of the code:

rarity = {api["rarity"]}
        if rarity:
            rarity="epico"
        else:
            rarity="epic"



            if rarity:
                rarity="un poco comun"
            else:
                rarity="uncommon"   



        
        print(f'Rareza: {rarity}')

But I can't figure out how to do it

This is the complete code that I am using:

import json
import requests

args= input("Escribe: ")

response = requests.get("https://jose89fcb.es/apifortnite/fish.php")
data = response.json()


match_found = False
for api in data['fish']:
    
    if args == api["name"]: 
        print(f'Imagen: {api["image"]}')
        print(f'Descripción: {api["description"]}')



        rarity = {api["rarity"]}
        if rarity:
            rarity="epico"
        else:
            rarity="epic"



            if rarity:
                rarity="un poco comun"
            else:
                rarity="uncommon"   



        
        print(f'Rareza: {rarity}')


        match_found = True
if not match_found:
    print("Error")

Could someone give me a hand? Thank you very much in advance!

A dictionary that takes English keys and returns Spanish values is what you are likely after:

rarity_en_to_sp = {
    "epic": "epico",
    "uncommon": "un poco comun",
}

rarity_en = "uncommon"
rarity_sp = rarity_en_to_sp.get(rarity_en, rarity_en)
print(f'Rarity: {rarity_en} Rareza: { rarity_sp }')

rarity_en = "unknown"
rarity_sp = rarity_en_to_sp.get(rarity_en, rarity_en)
print(f'Rarity: {rarity_en} Rareza: { rarity_sp }')

The use of get() here allows us to fall back to whatever the English version was in the event we don't have a translation yet.

This code should give you:

Rarity: uncommon Rareza: un poco comun
Rarity: unknown Rareza: unknown

I don't think you understand what if rarity means. That just means, check if its value is considered True or False. If a string has any content in it, this will be considered True. Perhaps you meant to check if its content was equal to the English version, and you want to translate it to the Spanish version?

You could do this via if-elif:

rarity = {api["rarity"]}
if rarity == "epic":
    rarity = "epico"
elif rarity == "uncommon":
    rarity = "un poco comun"

print(f'Rareza: {rarity}')

Or a dict:

translations = {
    "epic": "epico",
    "uncommon": "un poco comun"
}

rarity = translations[rarity]
print(f'Rareza: {rarity}')

You can use the Google Translate library if it's for a small-sized project.

Use pip to install googletrans library:

pip3 install googletrans

And then for example:

# import library
from googletrans import Translator, constants

# initialize translator instance
translator = Translator()

# translate something to English from Italian (English is the default)
translation = translator.translate("Ciao Mondo!")
print(f"{translation.origin} ({translation.src}) --> {translation.text} ({translation.dest})")

Output:
Ciao Mondo! (it) --> Hello World! (en)

If you get an error similar to this: AttributeError: 'NoneType' object has no attribute 'group' (which I got too), use these commands to install the specific version of the library that is used in the code above:

pip3 uninstall googletrans
pip3 install googletrans==3.1.0a0
