代码一：

names = ['张三', '李四', '王五', '赵六', '田七']
a = names[2]
b = names[-1]
print("{}去{}家做客".format(a,b))

代码二：

names = ['张三', '李四', '王五', '赵六', '田七']
a = names[-3]
b = names[-1]
print(a+"去"+b+"家做客")

student = ['张三', 18, '男', 180, 130]
print(student[0]+"的身高是"+student[3])

列表的count方法的功能是统计某个数值在列表中出现了几次。（ ）

代码一

number = [1,2,3,4,5,6,7]
del number[-1]
print(number)

代码二

number = [1,2,3,4,5,6,7]
number.pop()
print(number)

number = [1,5,2,4,5,6,0]
result = sorted(number)
print(number)
print(result)

number = [1,5,2,4,5,6,0]
print(sum(number)/len(number))
