while循环
#当某个条件成立后,持续循环#while 条件: #循环语句(循环体)‘‘‘def sumSum(star,end,step): i = star sum = 0 while i<=end: sum += i i += step return sumprint(sumSum(1,10,1))‘‘‘#死循环,内存填充,监控异常等用处‘‘‘while True: pas = input(‘请输入密码:‘) if pas == ‘123‘: print(‘输入密码正确!‘) break print(‘你输入的密码错误!‘)‘‘‘
for循环
#for循环nameList = [‘milk‘,‘jack‘,‘mary‘]index = 0while index < len(nameList): print(nameList[index]) index += 1print(‘for循环:‘)for name in nameList:#遍历循环 print(name)for name in range(0,len(nameList)): print(nameList[name])for one in range(1,10):#遍历循环数值 print(one)
break语句
跳出本层循环语句!
continue语句
结束本次循环!
