python中的迴圈分三種：while迴圈a = 0 b = 0while a<5: b += a # 相當於 b = b + a print(b) a += 1for迴圈b = 0for i in range(5): b += i print(b)遞迴迴圈b = 0def f(a): if a < 5: b += a print(b) f(a+1) else: returnf(0)

python 中的迴圈分三種：

while 迴圈

a = 0

b = 0

while a

b += a # 相當於 b = b + a

print(b)

a += 1

for 迴圈

b = 0

for i in range(5):

b += i

print(b)

遞迴迴圈

b = 0

def f(a):

if a

b += a

print(b)

f(a+1)

else:

return

f(0)
