| In 2.5, exec(open(filename)), where filename refers to a file with python code, executes the code. In 2.5, open returns an open file, but in 3.0, open returns a stream, and so exec (which wants "a string, file, or code object, not TextIOWrapper") returns an error. exec should probably be able to handle a stream. |

| There's 'execfile' in Lib/idlelib/PyShell.py...I'm looking for others. There is also a class of functions 'exec*' (and a related class, 'spawn*') in Lib/os.py that claims to do just what you want, but replacing the current process (or, in spawn*'s case, in a new thread). That said, I agree that exec should handle streams, and if you could give me a heads up as to where the code is for exec(), I could try my hand at a patch. |

| I'm actually quite new to Python. My current interpreter of choice is PostScript, followed by Matlab, but I've been discouraged from using either one here at EMC. (PostScript because it's obscure, Matlab because it's expensive!) Meanwhile, I'm on a wintel machine, making perusing the Python source tree difficult. So I'm not going to be much help in that regard. By the way, I was told that execfile is gone from python 3. --ms |

| Well, I think I found exec in bltinmodule.c, but execfile isn't in that file. [In the 3.0 tree.] |

| execfile is in Lib/idlelib/PyShell.py, and is an instance function, so it's not really standard for regular code, and would also be hard to use correctly. Sorry. |
