How to change webpage language from English to others in Edge using selenium python?

Question

I know how to change languages in selenium. You will say:

options = EdgeOptions()
options.use_chromium = True
options.add_experimental_option('excludeSwitches', ['enable-logging'])
prefs = {
        "translate_whitelists": {'fr':'en'},
        "translate":{"enabled":"true"}}
options.add_experimental_option("prefs", prefs)
driver = Edge(executable_path=PATH, options=options)

This works fine for all types of language but when i try to change from english to another language it doesnt work. For example:

prefs = {
        "translate_whitelists": {'en':'es'},
        "translate":{"enabled":"true"}}
options.add_experimental_option("prefs", prefs)

But if i say "translate_whitelists": {'es':'fr'}, It works. Basically you can convert to any output language but if the input language is english it doesnt work. Please help and explain

Answer 1

You can solve the problem by add_argument(). I tested it with the code you provided and it worked very well.

This is a simple example:

from msedge.selenium_tools import Edge, EdgeOptions

options = EdgeOptions()
options.use_chromium = True
options.add_argument("--lang=fr");
options.add_experimental_option('excludeSwitches', ['enable-logging'])
prefs = {
        "translate_whitelists": {'en':'fr'},
       "translate":{"enabled":"true"}}
options.add_experimental_option("prefs", prefs)

driver = Edge(executable_path=r"C:\Users\Administrator\Desktop\msedgedriver.exe", options=options)
driver.get("https://learn.microsoft.com/en-us/deployedge/configure-microsoft-edge")

Note: Modify the EdgeDriver path according to your situation

Answer 2

There are several flavors of English, so instead of simply en English you should distinguish between Great Britain English and United States English in case of translating from English.
So, instead of

"translate_whitelists": {'en':'es'}

Try this

"translate_whitelists": {'en-GB':'es'}

or this

"translate_whitelists": {'en-US':'es'}
