Python tuple,list习题

Python0906-第三天-作业
1.tuple的count和index方法的使用
2.定义list类型变量的两种方式
3.定义一个list,往list添加一个元素4
4.移除list中最后一个元素的两种方式
5.新定义一个list2将list2中的元素加到list中。
将list和list2合并产生一个新列表
6.对list进行排序，排序后倒置
7.整理浅拷贝和深拷贝的区别
8.定义dict的两种方式，访问dict中一个元素的vlaue

tuple_data = (1, 2, 3, 1, 1)
print(tuple_data.count(3))

print(tuple_data.index(3))
print(tuple_data.index(1, 1, 4))

tuple_data = ("123", 28, [1, 2, 3])
tuple_data[2][1] = 5
print(tuple_data)

list_data = [1, 2]
print(list_data, type(list_data))
list_data = [1]
print(list_data, type(list_data))
list_data = [1, ]
print(list_data, type(list_data))

# 空列表
list_data = []
print(list_data, type(list_data))
print(bool(list_data))

# 类型()
list_data = list()
print(list_data, type(list_data))

list_data = list("123")
print(list_data, type(list_data))

list_data = list((1, 2, 3))
print(list_data, type(list_data))

list_data[2] = 10
print(list_data)
# list_data[3] = 11

list_data.append(11)
print(list_data)

list_data = [1, 2.2, 1 + 2j, None, "123", b'123', (1, 23), [2, 3]]
print(list_data)

copy_list = list_data.copy()
data = 1
print(id(list_data))
