How to execute a file within the Python interpreter?

Several ways.

• From the shell

  python someFile.py
  

• From inside IDLE, hit F5.

• If you’re typing interactively, try this (Python3):

  >>> exec(open("filename.py").read())
  

• For Python 2:

  >>> variables= {}
  >>> execfile( "someFile.py", variables )
  >>> print variables # globals from the someFile module
