Python简单编程

简单的怎么答啊

Answer 1

• def GetNumOfBlocks(Layer):

• return sum([sum(range(1, k + 1)) for k in range(1, Layer + 1)])

使用 (传入 Layer 参数 4)：

print(GetNumOfBlocks(4))

输出：20

注意 return 行代码要缩进！

Answer 2

def sum(k):

s = 0

for i in range(k):

s = s + k

return(k)

n = int(input())

answer = 0
for i in range(i):
answer = answer + sum(i)

print(answer)
