Town Field Poem:
Cheng listens to the Tathagata language, the world name and benefit of Dayton. Be willing to do the Tibetan apostles, the broad show is by Sanfu mention.
I would like to do what I learned, to achieve a conscience blog. May all the Yimeimei, reproduce the wisdom of the body.

Code
Def Funwai (): wai=5 waitrue=2 def funnei (): print (waitrue) #这里对外部变量进行访问但未进行修改是可以的, but Wai =wai+1 #这里对外部变量不仅访问的了还修改了, there's a problem. return Funnei () Funwai ()
Result
============= restart:c:/users/administrator/desktop/mytest6.py =============2traceback (most recent): File "c:/users/administrator/desktop/mytest6.py", line ten, in <module> Funwai () file "c:/users/administrator/desktop/mytest6.py", line 7, in Funwai return funnei () file "c:/ users/administrator/desktop/mytest6.py ", line 6, in Funnei
