not working when using python -m <module> syntax

[badien]

• I try to use syntax python -m , nothing occurs. This is normal when using syntax python <script file>
• scenario:
  • write in __main__.py file with prog parameter as "app" under app folder inside project folder, Run command at project folder:
  • using python -m app --> nothing occurs
  • using python app/__main__.py --> it is ok

Please check, Thanks.
