run python script from python command line

iFunction · 03-14-2017, 10:25 AM

Hi there,

This has never occurred to me before, but up till now, my main.py file was inside the package, so I was able to run python, and from in there, just import the file and then run it. So now that I am learning about threading, it happened that I needed to run main.py from outside the package, as python was the main thread which in turn meant I could get the Daemon process I have written to stop.

So now main.py is outside the package, I now need a python window open to help me debug and test, but I can't for the life of me work out how you run a python file from inside python itself as in all my 4 years of part time python learning have I actually run a python script whist python has already been started.

How is this done please?

I cannot quite understand what you are after, but I can give a few suggestions.
Run a script using : python name_of_script.py
Write a function that starts when the script is made:

Code:

def start_function():
    pass # put code here

if __name__=='__main__':
    start_function()

In the above snippet you get the same behavior if you call the code as a script and if you load it as a package and run start_function() yourself.

Again, I hope this helps. If not, try to write what you are missing.

ok, so linux: in terminal:

Code:

someone@linux: python3

python3.....
>>>

from here, how can I run a python script?

If you run python3 from the same directory that your script resides (easiest way if you're pulling in other scripts from within the same directory):

>>> exec(open('./mypythonfile.py').read())

Why not run

Code:

python name_of_script.py

You could do the exec, but if it is just a function you run you can also:

Code:

>>>import name_of_script
>>>function()
