Similar to the Python library function `os.path.walk`. Traverses the tree of Python objects starting with `root`, depth first. Parent-child relationships in the tree are defined by membership in modules or classes. The function `visit` is called with arguments `(path, parent, children)` for each module or class `parent` found in the tree of python objects starting with `root`. `path` is a string containing the name with which `parent` is reachable from the current context. For example, if `root` is a local class called `X` which contains a class `Y`, `visit` will be called with `('Y', X.Y, children)`). If `root` is not a module or class, `visit` is never called. `traverse` never descends into built-in modules. `children`, a list of `(name, object)` pairs are determined by `tf_inspect.getmembers`. To avoid visiting parts of the tree, `children` can be modified in place, using `del` or slice assignment. Cycles (determined by reference equality, `is`) stop the traversal. A stack of objects is kept to find cycles. Objects forming cycles may appear in `children`, but `visit` will not be called with any object as `parent` which is already in the stack. Traversing system modules can take a long time, it is advisable to pass a `visit` callable which blacklists such modules. Args: root: A python object with which to start the traversal. visit: A function taking arguments `(path, parent, children)`. Will be called for each object found in the traversal.
