[Tutor] Consequences of removing python3-venv

[Jim]

My Linux mint18 system recently wanted to up date python 3.6. When I 
clicked install I got the following message:

The following 2 packages will be removed:
python3-dev
python3-venv

I have 2 virtual environments installed: python 3.5.2 & 3.6.7.

Listing the various pythons I have installed shows:

/usr/bin/python3m-config -> python3.5m-config

So will allowing the update harm my virtual environments?

I really don't want to reinstall them.

thanks,  Jim
