λ和列表解析

%下面是lambda的示例，它包含三个参数并添加前两个参数。
1 my_function = lambda a, b, c : a + b
my_function(1, 2, 3)

3

my_list = []
for number in range(0, 1000):
    if number % 2 == 0:
        my_list.append(number)
my_list

[0,
 2,
 4,
 6,
 8,
 10,
 12,
 14,
 16,
 18,
...
...
998]

%与上面相同效果
1 my_list = [number for number in range(0,1000) if number % 2 == 0]
my_list

[0,
 2,
 4,
 6,
 8,
 10,
 12,
 14,
 16,
 18,
...
...
