操作列表

for 循环

magicians = ['alice', 'david', 'carolina']
for magician in magicians:
    print(magician.title()+", that was a great trick!")
    print("I can't wait to see your next trick,"+magician.title()+"\n")
print("Thank you, everyone. That was a great magic show!")

1.range() 让你能够轻松地生成一系列的数字。

for values in range(1,6):
    print(values)
2.使用range（）创建数字列numbers = list(range(1,6)print(numbers)

3.使用range（）指定步长
even_numbers = list(range(2,11,2)) 
print(even_numbers)
4.对数字列表执行简单的统计计算
digits = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0] 
 min(digits) 最小值
 max(digits) 最大值
 sum(digits) 总和


切片
1.players = ['charles', 'martina', 'michael', 'florence', 'eli']

print(players[0:3])
2.如果你没有指定第一个索引，Python将自动从列表开头开始
players = ['charles', 'martina', 'michael', 'florence', 'eli'] 
print(players[:4])
3.要让切片终止于列表末尾，也可使用类似的语法
players = ['charles', 'martina', 'michael', 'florence', 'eli'] 
print(players[2:])

遍历切片

players = ['charles', 'martina', 'michael', 'florence', 'eli']

print("Here are the first three players on my team:")

❶ for player in players[:3]:

　　 print(player.title())

复制列表

my_foods = ['pizza', 'falafel', 'carrot cake']
friend_foods = my_foods[:]
print("My favorite foods are:")
print(my_foods)

print("\nMy friend's favorite foods are:")
print(friend_foods)

元组

dimensions = (200, 50)
print(dimensions[0])
print(dimensions[1])

#修改元组的变量
dimensions = (200, 50)
print("Original dimensions:")
for dimension in dimensions:
    print(dimension)
dimensions = (400, 100)
print("\nModified dimensions:")
for dimension in dimensions:
    print(dimension)
