lst.pop(i) if in above scenario, the correct way is to first store the modification somewhere else. Iterate the list entirely one time. Can use list.copy() or list[:] as the orignial list. Another example is looping through dictionary keys: d = {'a'=1, 'b'=2, 'c'=3} for key...
Note: If your functions needs several different return types, then you’re dealing with a more complex scenario. In this case, you can get some help from How to Use Type Hints for Multiple Return Types in Python.Once you’ve coded describe(), you can take advantage of a powerful Python...
