To add a new element to an array, use the append() method. It accepts a single item as an argument and append it at the end of given array.SyntaxSyntax of the append() method is as follows −append(v) Where,v − new value is added at the end of the array. The new value ...
We can add list items using the append() method by specifying the element we want to add within the parentheses, like my_list.append(new_item), which adds new_item to the end of my_list.ExampleIn the following example, we are adding an element "e" to the end of the list "list1"...

result[key] = max(item,key=item.get) 结果如下: result Out[94]: {'order1': 'room1', 'order2': 'room3'} (3)字典的排序:sorted()函数 import operator dic = {(1, 2): 3, (1, 3): 4, (4, 5): 14} ##字典的key可以是元组; ...
