How can I step to use the python debugger to break at every function call?
===

I want to closely monitor the chain of function calls which are called from a certain function.

    import pdb; pdb.set_trace()
    res = api.InsertVideoEntry(video_entry, video)

I'm looking for a way to easily see that `api.insertVideoEntry(video_entry, video)` calls `foo()` which calls `bar()` which calls `baz()`,

Here's a really crude diagram to show what I mean.  I don't need it in this form, but this is the kind kind of information I'm looking for.

    api.insertVideoEntry()
        foo()
            bar()
                baz()
                baz2()
            log()
        finish()
