3.1. 列表
# 定义一个列表对象
# alist = []
alist = list()
print(f'{alist = }, {type(alist) = }')
# CRUD 增删改查
alist.append(1)
alist.append(2)
alist.append(3)
print(alist)
alist.insert(0, 9)
print(alist)
element = alist.pop() # 弹出
print(alist, element)
# 指定下标弹出元素
element = alist.pop(0)
print(alist, element)
# 指定元素删除
alist.remove(2)
print(alist)
# 修改
alist[0] = 666
print(alist)运行结果如下图所示：
