#1测试判断用户与密码是否正确：import getpassusername = "llz"password = "123455"_username = input("请输入用户名:")#assword = getpass.getpass("请输入密码:")_password = input("请输入密码:")if _username == username and _password == password:    print("wlelcome user {name} longin ...".format(name = username))else:    print("Invalid user or name!")

#2猜年龄的游戏1：age_of_oldboy = 70guess_age = int(input("guess oldboy_age:"))if guess_age == age_of_oldboy :    print("yes,you got it!")elif guess_age > age_of_oldboy:    print ("guess smaller...")else:    print("guess it bigger...")

#3猜年龄的游戏.循环方法01：age_of_oldboy = 56count = 0while count < 3:    guess_age = int(input("guess oldboy_age:"))    if guess_age == age_of_oldboy:        print ("yes,you got it!")        break    elif guess_age > age_of_oldboy:        print ("guess smaller...")    else:        print("guess it bigger...")    count +=1else:    print ("your tried more than 3 times...")

#4猜年龄的游戏.循环方法02：age_of_oldboy = 56count = 0for count in range(3):    guess_age = int(input("guess oldboy_age:"))    if guess_age == age_of_oldboy:        print ("yes,you got it!")        break    elif guess_age > age_of_oldboy:        print ("guess smaller...")    else:        print("guess it bigger...")else:    print ("your tried more than 3 times...")

#5：打印循环数字：for i in range(9):    print("______",i)    for j in range(9):        print(j)    if i > 5:        print("end!")        break

#6测试模块打印目录：import  oscmd_res = os.popen("dir").read()print("-->",cmd_res)os.mkdir("new_dir")
