It's oddly difficult to glean from the official documentation the correct syntax for superclass initialization. |

The __init__() method isn't a feature of super(). It is a feature of the class being called. |

True enough, however, no search I could come up which included the term "super" or "__init__" returned a document near the top of the search which showed how to chain a superclass initializer. This can be confusing, as there are 2 syntaxes for doing this. |

The primary documentation for super() is here: https://docs.python.org/3/library/functions.html#super At the bottom it references a guide to using super() that you might find helpful: https://rhettinger.wordpress.com/2011/05/26/super-considered-super/ The standard library source code has many examples. In particular, the argparse module makes heavy use of super(): https://github.com/python/cpython/blob/3.8/Lib/argparse.py The tutorial provides some light discussion: https://docs.python.org/3/tutorial/classes.html#multiple-inheritance There is also an FAQ entry: https://docs.python.org/3/faq/programming.html#how-do-i-call-a-method-defined-in-a-base-class-from-a-derived-class-that-overrides-it There is also extensive coverage on StackOverflow: https://stackoverflow.com/search?q=%5Bpython%5D+super Hope you find these links helpful. |
