Using the Python interpreter

[tkpmep]

Instead of starting IDLE as I normally do, I started the Python
interpreter and tried to run a program. I got a Python prompt (>>>),
and then tried unsuccessfully to run a Python script named Script1.py
that runs perfectly well in IDLE. Here's what I did:
Traceback (most recent call last):
File "<stdin>", line 1
python Script1.py
SyntaxError: invalid syntax

I can load it (and have it execute) by typing
0
1
2
3
4

and if I edit it, I can then execute it by reloading it
0
1
2
3
4
<module 'Script1' from 'Script1.pyc'>

But this seems contrived - is there no way to repeatedly run Script1
from the interpreter without reloading it?

Why dont you wrap the code into a procedure (a def statement) in your script1
file import it using the from xxx import yyy statement. Then you can use it
over and over.

By the sounds of it your script is full of inline code that is executed when
its imported and therefore only runs once. To get it to re-run you have to
repeatedly import it. Your really should only need to do this under very
specific circumstances.

You need to do this from a Windows command line, not from Python.

C:\Python25>python Script1.py
Hello, world!

You want execfile:
