Yes, it is. That's why Python 3 forbids it::

It's fixed already in Python 3.
Please use Python 3 when teaching to students.

I teach intro to programming using Python. In my first assignment, students
are asked to assign variables of different types and print out the values.
One student (who really did not understand Booleans) turned in the following

I don't think I'll ever agree with you on this one.
"then", to me, implies the code following it is always executed.
"else" implies it's conditional.

No.
.NET Core (what the OP asked about which is not .NET) is a cross-platform
framework. Obviously Python and .NET differ in runtime semantics with
respect to the original source code, however they are now roughly equiva

Yes, using a "fuse" use-space filesystem, you can mount things as a
