Top of that stack is current scope, the bottom of that stack is all scopes' parent. Invoking `var/find_var` can `new/find` variable in current scope. Invoking `enter_local_scope/leave_local_scope` can create or destroy local scope. A `scoped_function` will take a `function` as input. That function will be invoked in a new local scope. é)Úprint_functionN)Ú get_cur_scopeÚenter_local_scopeÚleave_local_scopeÚvarÚfind_varÚscoped_functioncCsHttddƒ}|durtƒt_ttjƒdkrtj tjj  ¡¡tjdS)z@ Get current scope. :rtype: paddle.fluid.core.Scope Ú cur_scopeNréÿÿÿÿ) ÚgetattrÚ __tl_scope__Úlistr ÚlenÚappendÚpaddleZfluidÚcoreZScope)Zcur_scope_stack©rúPD:\Projects\ConvertPro\env\Lib\site-packages\paddle/fluid/default_scope_funcs.pyr.s  rcCstƒ}| ¡}tj |¡dS)z!
