Python学习一之列表类型

1.声明一个列表并打印

cast = ["cleese", "Palin", "Jones", "Idel"];\
       print(cast);

运行结果：

['cleese', 'Palin', 'Jones', 'Idel']

2.获取列表的长度

print(len(cast));

运行结果：4

3.在列表尾部添加一个列表项

cast.append("Gilliam");\
			 print(cast);

运行结果：['cleese', 'Palin', 'Jones', 'Idel', 'Gilliam']

4.在列表尾部移除一个列表项

cast.pop();\
	     print(cast);
fav_moves = ["The Holy Grail", "The Life of Brian", "The Meaning of Life"];


运行结果：['cleese', 'Palin', 'Jones', 'Idel']




5.在列表种添加一个列表集合

cast.extend(["Gilliam", "Chapman"]);\
			print(cast);
运行结果：['cleese', 'Palin', 'Jones', 'Idel', 'Gilliam', 'Chapman']




6.删除指定的列表项

cast.remove("Chapman");\
			 print(cast);
运行结果：['cleese', 'Palin', 'Jones', 'Idel', 'Gilliam']




7.在列表指定位置插入列表项

cast.insert(0, "Chapman");\
	       print(cast);
运行结果：['Chapman', 'cleese', 'Palin', 'Jones', 'Idel', 'Gilliam']




8.循环遍历列表
fav_moves = ["The Holy Grail", "The Life of Brian", "The Meaning of Life"];
for each_flick in fav_moves:\
	    print(each_flick);
运行结果：

The Holy Grail

The Life of Brian

The Meaning of Life
