已回答
Hi, I screen cut a part of my intelliJ, I noticed there is a folder named vent marked in red, I donot know what that means, and i donot remember how it appeared, recently, i downloaded beautifulsoup and also git pull .
right now, I havent met up any coding problem, but i am wondering how and why this red folder showed up ? Thanks for the explaination.

I would guess the folder name is a mistype of 'venv', which is a default name for virtualenv environment. More info here: https://virtualenv.pypa.io/en/latest/
PyCharm creates a new virtualenv environment automatically when you create a new interpreter, and marks it as "excluded" (red color) to tell IDE that it's contents shouldn't be indexed.
uh, I see, thank you very much. now I understand, and will not be worried about this anymore.
