Cannot run python file [duplicate]

Question

I am trying to run a stand-alone python file partitions.py that is in my home folder. When I type the command "python3 partition.py" the script runs.

However, when I type "python3 -m partition.py" it gives me an error "/usr/local/bin/python3: No module named partition.py"

I do not know why this is the case. Any help would be greatly appreciated. Thanks

Is the file partition.py located in a directory that is in your PYTHONPATH environment variable? — senshin

Because there isn't a module named partition.py; there is a file named partition.py. The corresponding module is named partition, which is what the -m flag expects. Please see the linked duplicate for a full overview of -m`. — Karl Knechtel

To run the module as script directly use:

python3 -m partition

(without the .py ending).

That will cause python to search sys.path for a module called partition and execute it. partition.py in this context would mean a module in a file partition/py.py.

In your case the home directory presented in sys.path.

See the doc, specifically that the module must be on the path, and the extension shouldn't be included.
