如何在我的 python 代码中正确集成谷歌翻译器 api？

Question

I'm actually doing a bot that forward messages from a channel to another channel. It apply some changes like replace words, avoid voice or images ( as defined in the upper part of my code), and works perfectly this way.

But i'd like to add a functionally that translate the message AFTER the operations performed on it and forward the result like that:

" [message forwarded after operations done on it]

---

[ message forwarded after operations done on it AND translated to French]

"

So there's the actual code, I imported google translate api, but don't understand where doing the operations, and how to concatenate without sending me those errors (cf. screenshot)

Based from the example of googltrans , the sample usage of it is:

from googletrans import Translator

translator = Translator()
trans_text = translator.translate('안녕하세요.')
print(trans_text)
 # output: Translated(src=ko, dest=en, text=Hello., pronunciation=None, extra_data="{'confiden...")
print(trans_text.text) # use .text to get the translated word
 # output: "Hello."

Based from your error you tried to use event to use the attributes of the Translator() class. Instead of using event , you should create an object using Translator() and use the object to perform translation.

Assuming message_text is a string. Your code should somewhat look like the one below.

from googletrans import Translator

translator = Translator()
message_translated = translator.translate(message_text, dest='fr', src='en')
print(message_translated.text) # this should contain the translated text

Keep in mind that googletrans is not the official Google Translation API so there will be limits applied if you are sending too much translation requests. I highly suggest to use the official Google Translate API so you won't be encountering limitation issues moving forward. See warning below from googletrans documentation:

• The maximum character limit on a single text is 15k.
• Due to limitations of the web version of google translate, this API does not guarantee that the library would work properly at all times. (so please use this library if you don't care about stability.)
• If you want to use a stable API, I highly recommend you to use Google's official translate API .
• If you get HTTP 5xx error or errors like #6, it's probably because Google has banned your client IP address.
