Traversing heaps

import tlhelp32

              "  Handle:            %s\n" % module.handle,
              sep="")

Traversing processes

              "  Name:          %s\n" % process.name,
              sep="")

Traversing threads

import tlhelp32

    for idx, thread in enumerate(snapshot):
        print(f"Thread #{idx}")
        print("  ID:            %s\n" % thread.pid,
