faulthandler.enable() is a Python function in the Faulthandler Module category. Enables the fault handler for crashes (segfaults, etc.). Dumps tracebacks on fatal signals. The syntax is faulthandler.enable(file=sys.stderr, all_threads=True). Returns: None. A typical example: import faulthandler faulthandler.enable() # Python will dump traceback on crash.
