Python中的列表（list）是一种有序的集合，可以包含任意类型的元素。列表使用方括号[]来表示，每个元素用逗号隔开。
l0 = []
print(l0, type(l0))
l2 = [10, 3.14, "hello", False, None, l0]
print(l2, type(l2))l3 = list()
print(l3, type(l3))
l4 = list("hello world")
print(l4, type(l4))
l5 = list(range(10))
print(l5, type(l5))# 基础数据类型：一个变量只能存储一个数据
a = 10
f = 3.14
b = True
s = "hello"
n = None# 列表 可以存储 多个数据
l6 = [a, f, b, s, n]
length = len(l6)
print(length)print(l6[0], l6[4])# 直接获取元素 不关注索引
for e in l6:print(e)for i in range(len(l6)):print(i, l6[i])l7 = [10, 5, 50, 60, 80, 70, 90, 9, 25]
# l7 = [-1, -2, -3]# print(max(l7))# max_value = 0
# for e in l7:
# if e > max_value:
# max_value = e
# print(max_value)# max_value = None
# for e in l7:
# if max_value is None:
# max_value = e
# else:
# if max_value < e:
# max_value = e
# print(max_value)smax_value = l7[0]
for i in range(1, len(l7)):# print(l7[i])if max_value < l7[i]:max_value = l7[i]
print(max_value)
