I am trying to install flask. [Docs say](https://flask.palletsprojects.com/en/2.0.x/installation/#create-an-environment) to make an environment:

> 
> Create an environment
> 
> 
> Create a project folder and a venv folder within:
> 
> 
> Windows
> 
> 
> 
> ```
> mkdir myproject
> cd myproject
> py -3 -m venv venv
> 
> ```
> 
> 

How should I run those?

* one line at a moment and the other?
* all in a one or write a *`bash`-y* script?

I am on `cmd.exe`, Windows 7.
