列表推导式与字典推导式 - 噜啦
博主: 噜啦 · 2019-09-07 · via 噜啦 - 字典

代码

#列表推导式
#C语言编程思维的写法
a_list = []
for i in range(1,11):
    if i % 2 == 0:
        a_list.append( i*i )

print(a_list)

#Python中的写法

b_list = [i*i for i in range(1,11) if i % 2 == 0]
print(b_list)

#字典推导式
chinese_zodiac = '猴鸡狗猪鼠牛虎兔龙蛇马羊'

#之前的方法
# z_num = {}
# for i in chinese_zodiac:
#     z_num [i] = 0

#现在的写法
z_num = {i:0 for i in chinese_zodiac}
print(z_num.keys())
