一:Python的用户输入:
1.1 Python的输入
#!/usr/bin/env python # -*- coding: utf-8 -*- # Author:FlyFish #import getpass _username = "zhangyy" _password = "abc123" username = input("username:") password = input("password:") ### password = getpass.getpass("password:") if _username == username and _password == password: print("Welcom user {name} login".format(name=username)) else: print("Invalid username or password ")
二:if....else 循环:
在程序里设定好你的年龄,然后启动程序让用户猜测,用户输入后,根据他的输入提示用户输入的是否正确,如果错误,提示是猜大了还是小了
注释:
外层变量,可以被内层代码使用
内层变量,不应被外层代码使用
#!/usr/bin/env python # -*- coding: utf-8 -*- # Author:FlyFish age_of_zhangyy = 26 guess_age = int(input("guess zhangyyy age:")) if guess_age == age_of_zhangyy: print("yes,yo go it") elif guess_age > age_of_zhangyy: print("think smaller...") else: print("think bigger")
三:while的循环
#!/usr/bin/env python # -*- coding: utf-8 -*- # Author:FlyFish count = 0 while True: print("count",count) count = count + 1
#!/usr/bin/env python # -*- coding: utf-8 -*- # Author:FlyFish age_of_zhangyy = 26 count = 0 while True: if count == 3: break guess_age = int(input("guess zhangyyy age:")) if guess_age == age_of_zhangyy: print("yes,yo go it") break elif guess_age > age_of_zhangyy: print("think smaller...") else: print("think bigger") count+=1
#!/usr/bin/env python # -*- coding: utf-8 -*- # Author:FlyFish age_of_zhangyy = 26 count = 0 while count<3: guess_age = int(input("guess zhangyyy age:")) if guess_age == age_of_zhangyy: print("yes,yo go it") break elif guess_age > age_of_zhangyy: print("think smaller...") else: print("think bigger") count+=1 if count ==3: countine_confirm = input("do you want to guessing....") if countine_confirm !='n': count ==0 else: print("you have tried too many times..fuck off")
三:Python的模块知识:
Python的强大之处在于他有非常丰富和强大的标准库和第三方库,几乎你想实现的任何功能都有相应的Python库支持,以后的课程中会深入讲解常用到的各种库,现在,我们先来象征性的学2个简单的。
