　　2019.5.7，从今天开始跟着“老男孩教育”的“金角大王”学习python开发。

　　首先还是得下载python3.x，至于下载哪个版本各执己见，我下载的是python3.6.8，没有选择3.7的版本是因为3.7版本貌似不会自动安装pip，之前试过一次，不知道是我电脑问题还是什么？直接在cmd下输入pip报错。

　　下载步骤：（1）到python官网https://www.python.org/

　　　　　　　（2）选择Downloads --> Windows

　　　　　　　（3）选择要下载的版本，注意是32位还是64位，下载executable installer文件（即可执行文件）。

　　安装步骤：注意勾选需要的选项，如图：

python3安装完成后就该安装pycharm了，当然也可以直接用python3自带的IDLE编辑运行。在此讲一下pycharm，pycharm分为专业版（professional）和社区版（community），如果只是新手刚刚开始学python的话，社区版就可以满足需求，还是免费的。但是如果要使用pyrhon进一步开发的话还是得选择专业版。当然，专业版也有激活方法。

pycharm专业版下载步骤：

　　（1）到官网http://www.jetbrains.com/pycharm/

　　（2）DOWNLOAD NOW --> 选择professional --> DOWNLOAD

安装/激活步骤：

　　（1）下载破解补丁，链接：https://pan.baidu.com/s/11UgcwO7-6u1fryRSQYYijw 提取码：4i2l

　　（2）将破解补丁复制到pycharm的bin目录下：

　　（3）在pycharm安装目录下的找到bin目录，打开pycharm64.exe.vmoptions文件，操作如图所示：

　　（4）打开pycharm，选择Activation code方式激活，这个KEY貌似只支持2019.1版本。在框中填入如下代码：

作业1：编写登陆接口

输入用户名密码
认证成功后显示欢迎信息
输错三次后锁定

程序代码如下：

 1 # Author:K
 2 count = 0
 3 while count < 3:
 4     count += 1
 5     login_user = input("Please input account number:")
 6     login_password = input("Please input password:")
 7 
 8     with open(r"D:\PycharmProjects\python learning\day01\homework1\Locked",'r',encoding='gbk') as f1:
 9         if login_user in f1.read(): #判断用户名是否在被锁文件中
10             print("Sorry!Your account number was locked!")
11             break
12         else:

15                 for contents_account in f2: #在文件中匹配帐号和密码
16                     if login_user == contents_account.split()[0] and login_password == contents_account.split()[1]:

22                         break
23         if login == 1:
24             break
25 else: #若输入的次数大于3次，则锁定账户，将账户名写入“被锁文件”中
26     with open(r"D:\PycharmProjects\python learning\day01\homework1\Locked",'a',encoding='gbk') as f3:
