Initialising the class variable at the end of the object initialisation method. This will help to run this library smoothly in use cases such as in Jupyter or ipython or spyder or GUI or other cell based execution. Will solve problems highlighted repeatedly in these stack overflow posts (With 1000s of views, current suggestions are some non-elegant work arounds such as importlib.reload(turtle) or or try-except and initializing again in the except as the _RUNNING becomes true at the end of last run or manually setting the _RUNNING flag). More logical turn this to True after the initialization rather than during terminator exception. https://stackoverflow.com/questions/45534458/python-turtle-terminator-even-after-using-exitonclick https://stackoverflow.com/questions/34956937/weird-terminator-error-when-running-python-3-turtle-in-os-x https://stackoverflow.com/questions/70252586/turtle-module-for-langtons-ant-in-python-giving-me-raise-terminator-turtle-ter https://stackoverflow.com/questions/58078376/a-function-i-created-can-only-be-called-once-second-time-it-shows-an-error https://stackoverflow.com/questions/54198108/how-can-i-close-a-window-after-using-turtle https://stackoverflow.com/questions/67734319/running-turtle-multiple-times-but-receiving-a-terminator-error-after-the-first-r https://stackoverflow.com/questions/43294665/turtle-done-not-working-in-spyder https://stackoverflow.com/questions/50438762/python-turtle-window-crashes-every-2nd-time-running https://stackoverflow.com/questions/41644324/how-to-close-python-turtle-properly https://stackoverflow.com/questions/41548813/using-turtle-module-exitonclick/70552164 https://stackoverflow.com/questions/66750634/why-do-i-get-a-terminator-error-when-i-run-this-program https://stackoverflow.com/questions/65546812/python-turtle-terminator https://stackoverflow.com/questions/61963565/why-do-i-keep-getting-a-terminator-error-for-python-turtle

Initialising the class variable at the end of the object initialisation method. This will help to run this library smoothly in use cases such as in Jupyter or ipython or spyder or GUI or other cell based execution as well as the usual self contained script or module execution.

Will solve problems highlighted repeatedly in these stack overflow posts (With 1000s of views, current suggestions are some non-elegant work arounds such as importlib.reload(turtle) or or try-except and initializing again in the except as the _RUNNING becomes true at the end of last run or manually setting the _RUNNING flag). More logical to turn this to True after the initialization rather than during terminator exception. Have tested it with various demo cases and examples. No problem found with this update.
