It is pretty much the same thing as you would get by choosing
Run -> Python Shell
from the IDLE window.
It is the Python interactive interpreter. You can type python
statements at that >>> prompt.
You can run programs from that prompt... but you have to
import them first.
Let's say you have a file foo.py
#foo.py
def bar(n):
print n
if __name__ == '__main__':
bar('module was run, not imported')
#end foo.py
If I run the program:
>python foo.py
module was run, not imported
But then you could in your Python Shell...
>>>import foo
>>>foo.bar('a test')
a test
Of course, foo.py needs to be on your sys.path for that to work....
