Having lists and dictionaries as default argument values is a bad
idea, because the same instance of list/dict will be used by all
objects instantiated using such constructor:
def appendItem(itemName, itemList=[]):
itemList.append(itemName)
return itemList
print(appendItem('notebook'))
print(appendItem('pencil'))
print(appendItem('eraser'))
Output:
['notebook']
['notebook', 'pencil']
['notebook', 'pencil', 'eraser']
