#1测试判断用户与密码是否正确：
import getpass
username = "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 = 70
guess_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 = 56
count = 0
while 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 +=1
else:
    print ("your tried more than 3 times...")

#4猜年龄的游戏.循环方法02：
age_of_oldboy = 56
count = 0
for 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  os
cmd_res = os.popen("dir").read()
print("-->",cmd_res)
os.mkdir("new_dir")
