16. Python Parameter Passing Mechanism (Edexcel 6.6 Subprograms)
Looks at a suitable model to describe the Python parameter passing mechanism. Also recommends that you regard passing parameters in Python as pass by object reference. Furthermore it recommends that you ignore pass by value and pass by reference as being a suitable description for parameter passing in Python. Please note: this video is beyond the scope of the GCSE but I would nevertheless recommend viewing it.
