When developing Python code, I often find myself needing to run "rm *.pyc" so that the interpreter will ignore any new changes that I have made to source files. It's really frustrating when forgotten.

Adding a flag to the reload builtin would go a long way to simplify this process.

[brettcannon]

I don't quite follow what you want. You say you want to *ignore* changes to source files, but that's the whole point of a reload. And I don't see how ignoring bytecode changes anything unless you are mucking with bytecode formats and don't want to have to continuously change the magic number.

[timClicks]

No no, I don't want to ignore source files. I want to be able to change a .py file, then reload in the Python shell and for the changes to be applied.

At the moment, .pyc files within a project complicate this.

[brettcannon]

Then I'm not understanding the problem as changes to source trump .pyc files in a reload(). It should make no difference that .pyc files even exist to a reload() as long as source is around.

Never heard back from OP.
