File I/O

May 17th, 2008
Hey guys, lately i've been having some trouble with file I/O but usually i don't heres an example of reading a file:
Python Syntax (Toggle Plain Text) 
  1. print "\nReading..."
  2.                     myfile = open('myfile.txt', 'r').read()
  3.                     print "\n",myfile
but is there and easier way to do that because when i try to run the program just stops, it didn't do that a couple hours ago when i first started writing the program, so any suggestions? thanks

Assuming that myfile.txt exists, this should work just fine. Works for me.
python Syntax (Toggle Plain Text) 
  1. myfile = open('myfile.txt', 'r').read()
  2. print "\n", myfile
