Fix Spelling and Grammar with language_tool_python and textblob

Below are two practical Python libraries for text processing. This function uses textblob's spelling correction along with language_tool_python, which applies grammatical corrections via the Language Tool API. I added these text processing transformations into my concept text generation app. These are free, public APIs up to around 20 requests per second. You can send both text and receive back an improved version of your text, ideally altering and improving your writing.

I found 2 errors when I piped the text of this post into the below code: the proper noun "textblob" corrected to "text blow's" and the word "app" corrected to "pp". Be sure to proof your results. Regardless, I like having these two Python tools in my bag!

Install
