Python for s60 输出重定向和模块列表

Python for S60是赛班系统的Python。既可以Interactive的输入命令，也可以运行脚本。帮助信息可以通过函数help获得，如查询有哪些modules,可以使用命令>>>help('modules')，或输入>>>help()，然后输入modules，不过由于module太多，显示的缓存太小，只能显示最后的一些modules。如何查看所有的输出，方法是将屏幕输出重定向到文件。导入sys模块，sys.stdout的值可能为<series60_console.Console instance at 0x17649b8>，只要将该属性设为文件的句柄就可以，文件句柄可以通过fh=open('filename','w')获得。给sys.stdout赋值前先保存该值以便恢复。将文件句柄赋予sys.stdout后，再输入>>>help('modules')或>>>print help('modules')屏幕无输出，查看fh对应的文件就可以看到所有的模块信息。最后有必要恢复sys.stdout的原值和关闭fh，fh.close()。
