When you start working on a Python project **for the first time**, create a virtual environment **<abbr title="there are other options, this is a simple guideline">inside your project</abbr>**.

/// tip

You only need to do this **once per project**, not every time you work.

///

//// tab | `venv`

To create a virtual environment, you can use the `venv` module that comes with Python.

  // Certain operations (like SYN_STREAM) need to synchronize on both the frameWriter (to do
  // blocking I/O) and this (to create streams). Such operations must synchronize on 'this' last.
