#小练习 输出模块中方法及其docstring

divide into python 中例子，输出模块的函数及docstring文档内容。

以下例子是通过调用getdoc模块中的main方法，输出imp_main模块中方法及docstring

imp_main.py :

#coding:utf-8#运行此模块时，调用此函数def runself():    'execute this method when running this module'    print "Running self to be used"#此模块被导入时，调用此函数def outUse():    print "When imported to be used"if __name__ == '__main__':    runself()else:    outUse()

getdoc.py

#coding:utf-8import imp_maindef main(module,space=15,collapse=1):    methodlist = [method for method in dir(module) if callable(getattr(module,method))]    docFunc = collapse and (lambda s:" ".join(s.split())) or (lambda s:s)    print '\n'.join(    "%s --> %s" % (method.ljust(space),docFunc(str(getattr(module,method).__doc__))) for method in methodlist)if __name__ == '__main__':    main(imp_main)    print '*'*60    main([])
