方法1：ok的

a = [1, 2, 3, 4, 5, 6, 7, 8]

# print(id(a))

# print(id(a[:]))

for i in a[:]:

if i > 5:

a.remove(i)

print(a)

# print(id(a))

2.filter

內建函數filter()官方文檔參考：https://docs.Python.org/3/library/functions.html#filter

a = [1,2,3,4,5,6,7,8]

b = filter(lambda x: x>5,a)

print(list(b))

運行結果：

3.列表解析

a = [1,2,3,4,5,6,7,8]
