如果两种方法都无法激活，可以加入激活群寻求帮助！
5.查看有效期
当你激活完毕后，PyCharm右下角会有个Registration小长条提示框，大致的内容为：You copy is Licensed to XXX意思就会告诉你：兄弟，你已经激活成功了，激活码的许可来源是：XXX。
查看有效期的步骤为点击：Help->About这里可以看到你的pycharm的版本号、许可来源、有效期、以及一些环境
服务器激活是没有期限的，即为永久有效
激活码激活的有效期到2089年的
三.汉化教程
Pycharm、IDEA等汉化教程
四、番外篇
1.pycharm官方使用手册
手册入口：https://www.jetbrains.com/help/pycharm/meet-pycharm.html
2.python入门与爬虫项目
这是我自己写的一个爬虫项目，主要功能是从网上爬取一些最近的电影名、列车号、航班号然后做增量修改到文件和Mongodb中去，感兴趣的同学可以看看，有不明白的地方可以在公众号里直接问我，项目入口：http://blog.csdn.net/u014044812/article/details/78894108
3.安装python解释器
很多同学在微信公众号问我怎么项目运行不了，结果是因为大家在安装pycharm后没有为项目选择解释器，如图：
解决办法是：直接点击此提示框右侧的：Configure Python interpreter 跳转设置去选择解释器
如果这里没有解释器，就点击右侧的+号，新建一个，选择好解释器之后等待一会，之前的`Configure Python interpreter`提示框就会消失
一些常用设置：
1. pycharm默认是自动保存的，习惯自己按ctrl + s 的可以进行如下设置：
1）. file -> Setting -> General -> Synchronization -> Save files on frame deactivation 和 Save files automatically if application is idle for .. sec 的勾去掉
2）. file ->Setting -> Editor -> Editor Tabs -> Mark modified tabs with asterisk 打上勾
2. Alt + Enter: 自动添加包
3. 对于常用的快捷键，可以设置为visual studio(eclipse...)一样的：
file -> Setting -> Keymap -> Keymaps -> vuisual studio -> Apply
4. Pycharm中默认是不能用Ctrl+滚轮改变字体大小的，可以在file -> Setting ->Editor-〉General中设置
5. 要设置Pycharm的字体，要先在file -> Setting ->Editor-〉Editor中选择一种风格并保存，然后才可以改变
6. 在setting中搜索theme可以改变主题，所有配色统一改变
