Output

输出量

cities are:  ['New Delhi', 'Mumbai']    cities are: ['New Delhi', 'Mumbai', 'Bangalore', 'Chennai']

Explanation:

说明：

• Initially there were two elements in the list ['New Delhi', 'Mumbai']

  最初，列表中有两个元素['New Delhi'，'Mumbai']

• Then, we added two more city names (two more elements) - 1) 'Bangalore' and 2) 'Chennai', by using following python statements:

  然后，我们使用以下python语句添加了另外两个城市名称(另外两个元素)-1) 'Bangalore'和2) 'Chennai' ：

cities.append('Bangalore');    cities.append('Chennai');

• 'Bangalore' and the 'Chennai' will be added at the end of the list named cities.

  “班加罗尔”和“钦奈”将添加到名为城市的列表的末尾。

• Then, we printed the updated list; the output will be a new list with 4 elements ['New Delhi', 'Mumbai', 'Bangalore', 'Chennai'].

  然后，我们打印了更新的列表； 输出将是一个包含4个元素的新列表['New Delhi'，'Mumbai'，'Bangalore'，'Chennai'] 。
