Please set to false by default

Please remove the == "true" so it can just be whatever the actual value is

Hmm I don't understand: the environment variables are not well-typed (i.e. they are strings). In that case the flag would evaluate to true all the time (as a non-empty string). Just like here

I'd have to check with an actual run or dig into the SDK, but I'm betting the create_new=False will be ok with False as a string (it's not checking it as a boolean).

so the variable should be boolean, (see here) and Python will convert any type to boolean, but with unexpected results :)
so the check for the "true" string is vital here for this to work

An alternative solution could be to use a library like https://pypi.org/project/environs/ to type the environment variables properly.

Environs looks cool, but I don't really want to introduce a new dependency right now. Sushant Divate (@sudivate) thoughts?

Looks good to me, for the scope of this PR lets typecast the string to bool in env_variables.py

| aml_workspace, e.aml_env_name, create_new=False) # NOQA: E501 | ||

| aml_workspace, e.aml_env_name, create_new=e.rebuild_env == "true") # |

(same as above)

That's right. It's confusing in Python. I would update env_variables.py to return a boolean (not string) value. E.g. return self._rebuild_env == "true"
…Python into cm/rebuild-environment-flag

Fixes #229 by allowing the AML Environment to be recreated instead of reused.
