Execute Python files directly in the terminal

• Open the terminal and cd to the Python file directory (you can also drag and drop the Python file directly to the terminal)

• 

• run the file directly

  $ Python main.py

• report an error

    File "main.py", line 2

      print 'hello Python'

                         ^

  SyntaxError: Missing parentheses in call to 'print'

• python3 does away with this usage. Use print('hello Python") or print('hello python')

• Change the code to continue execution

  print ('hello Python')

  
  

• $ Python main.py
