py3,休息時間玩點小把戲

 

100之內奇數:app

ls = [x for x in range(100) if x % 2 == 1]

spa

100之內偶數:code

ls = list(x for x in range(100) if x % 2 == 0)blog

 

20之內的2次方:ci

ls = list(x * x for x in range(20))

class

斐波那契數列 Fibonacci :
一、一、二、三、五、八、1三、2一、34  ……  數列特色:該數列從第三項開始,每一個數的值爲其前兩個數之和import

ls = [1, 1]
for i in range(2, 20):
    ls.append(ls[i - 2] + ls[i - 1])
    print(ls)

 

試一下:im

import copy
a = True
a = 123
a = "123"
a = (1, 2, 3)

a = [1, 2, 3]
a = {"x":1,"y":2}
b = copy.copy(a)
c = copy.deepcopy(a)

print(id(a))
print(id(b))
print(id(c))
