python - error when using tkinter + sqlite3 -


I'm trying to use sqlite3 in a guinea here, and when I'm using geo Try to compile the code, return this error 

  file "/home/armando/Documents/curso/python_projects/sqlite3.py", line 3 syntax error: non-ASCII Python_projects / sqlite3.py on character '\ xc3' file / home / armando / document 3 / line / 3, but no encoding is declared;   
 How can I solve it?  
 Thanks    P> Light and Peace!  
  
 
 
 see p. 263 -  
 You must declare your source at the top of the module Your encoding:  
  #! / Usr / bin / python # - * - coding: utf-8 - * -   
 Replace UTF-8 with the encoding that you saved the file.
