[Python]B06─流程控制(control flow)

Hi! 大家好，我是Eric，这次教大家Python的流程控制(control flow)!

■ 流程控制(control flow)

if-elif-else，条件判断，可依需要任意配置elif的数量

x = 15    if x == 0:     print(x)elif x > 0:     print(x)elif x < 0:     print(x)else:     print(x)

for，重複执行的迴圈，in右边的物件为迭代器，为一个序列

for N in [2,3,5,7]    print(N, end=" ")        for i in range(10)          #迭代器最常用的是range()    print(i, end=" ")       list[range(5,10)]list[range(0,10,2)]

while，保持迴圈直到不再满足某种条件

i = 0while i < 10:   print(i, end=" ")   i = i + 1

break跳出整个迴圈；continue跳出当前迴圈，进入下一个迭代中while True迴圈，一直迴圈直到遇到一个跳出语句

a, b = 0, 1amax = 100L = []while True:    (a, b) = (b, a + b)    if a < amax:          #当a=amax时跳出整个迴圈          break         L.append(a)print(L)  for n in range(20):    if n/2 == 0:        #当n/2==0时跳过当次迴圈       continue    print(n, end=" ")
