Well, if you've written your program as a .py file, the usual technique is
to enter an import statement to the interactive interpreter. The code is
executed as the import proceeds. The __name__ == _"__main__" trick is
usually used to run test code in a module intended primarily for import by
other code rather than for execution as a program.

Of course, this only works once, because further imports will assume they
can use teh already-imported module. To get subsequent modifications of the
script to work you have to use reload(mdulename), which will force
execution.

It's a slight pain that the first import is different from all the others,
but never mind.
