## ### while 循环语句
#打印0-10coent = 0while coent <= 10: print(coent) coent+=1
#打印0-10 之间的偶数
coent = 0while coent <= 10: if coent%2 == 0: print(coent) coent+=1
#打印0-10 之间奇数
coent = 0while coent <=10: if coent%2 ==1: print(coent) coent+=1
#死循环
# import time# num = 0# while True: # print(num) # time.sleep(1) # num+1

# 1.循环验证用户输入发用户名与密码# 2认证通过后,运行用户重复执行命令# 3当用户输入命令exit时,则退出整个程序# (1)# name = "var1"# passwrod = "12345"# while True: # inp_name = input("用户名>>>:") # inp_pwd = input("密码>>>>:") # if inp_name == name and inp_pwd == passwrod: # print("登录成功-->准备走下面") # while True: # cmd = input(">>>>:") # if not cmd:continue # if cmd =="exit": # break # print("run <%s>"%cmd) # else: # print("用户名或密码错误") # continue # break
