Python init template (app) gets class name wrong

[garnaat]

If you do:

$ mkdir pythonhw
$ cd pythonhw
$ cdk init --language python

The class name used in the import statement in app.py is not properly templatized and does not match the name of the class in the package directory file. This causes an error like this:

(.env) $ cdk synth
Traceback (most recent call last):
  File "app.py", line 5, in <module>
    from pythonhw.pythonhw_stack import PyStack
ImportError: cannot import name 'PyStack' from 'pythonhw.pythonhw_stack' (/Users/garnaat/projects/cdkdev/pythonhw/pythonhw/pythonhw_stack.py)
Subprocess exited with error 1

errata. "cdk init app --language=python"

Another issue I ran into is that if your project directory has a hyphen, the generated python module will be invalid.

Yep. See #2180.
