流程控制

基本

break 跳出当前循环

continue 结束本次自己所在的循环

if-else结构

age = 3
if age >= 18:
    print('adult')
elif age >= 6:
    print('teenager')
else:
    print('kid')

while 结构

count = 0
while (count < 9):
   print 'The count is:', count
   count = count + 1

for 结构

fruits = ['banana', 'apple',  'mango']
for fruit in fruits:  # 输出每种水果
   print ('当前水果: %s'% fruit)


sum = 0
for x in range(101): # 计算1-100的整数之和
    sum = sum + x
