_ Author _ = 'admin' Class CaptchaImage: Def queue (self, arr = list ()): Return arr Def InsertCode (self, code ): Self. queue (). append (code) If _ name __= = '_ main __': C = CaptchaImage () C. InsertCode (1) B = CaptchaImage () B. InsertCode (2) Print (B. queue ()) Print (c. queue ())

The output result of code execution is:
