How to check available Python libraries on Google App Engine & add more?
如何在Google App Engine上检查可用的Python库并添加更多?
Is SQLite available or we must use GQL with their database system only?
是SQLite可用还是我们必须只在他们的数据库系统中使用GQL?
Thank you in advance.
先感谢您。

SQLite is there (but since you cannot write to files, you must use it in a read-only way, or on a :memory: database).
SQLite就在那里(但由于你无法写入文件,你必须以只读方式使用它,或者在:memory:database中使用它)。
App engine docs do a good job at documenting what's there. You can add any other pure-python library, typically as a zipfile of .py (NOT .pyc) files to upload in the main directory of your app (you can directly import from inside the zipfile, of course).
App引擎文档在记录存在的内容方面做得很好。您可以添加任何其他纯python库,通常作为.py(NOT .pyc)文件的zip文件上传到您的应用程序的主目录中(当然,您可以直接从zipfile中导入)。
A few more pure-Python third-party libraries included with app engine are listed and documented here -- the paragraph on zipimport at this URL has a bit more details on the ways and limitations of using zipfiles to add more third-party pure-Python libs to your app.
