To disassemble swf call swf module::

python3 -m pyzza.swf file.swf -d

This form can also strip unneeded tags, optimize bytecode, etc. Look --help.

To compile python-like language (pyzza) file::

python3 -m pyzza.compile -l library.swf file.py

This produces file.swf. library.swf is usually file from flex SDK, it's contained in playerglobal.swc which you use to compile actionscript when using mxmlc. You can also add your own library.
