There are several snippets in both main.py and logic.py related to managing save filenames and managing/forcing extensions.

main.py : Windows.get_save_path():

# The file is not a . (dot) file and there's no extension, so add
# .py as default.
path += ".py"

logic.py: Editor.rename_tab():

if not self.has_python_extension(os.path.basename(new_path)):
    # No extension given, default to .
    new_path += ".pyl"

logic.py: Editor --> python_extensions defined in several places

self.python_extensions = [".py", ".pyw"]

and

pyextensions = [".pyw", ".PYW", ".py", ".PY"]

and

for mode_name, mode in self.modes.items():
    if mode.file_extensions:
    extensions += mode.file_extensions
