Run Python script from anywhere

Question

I'm defining a bash function in my .bash_profile so that I can run a certain Python script from any directory. My function is something like this:

func()
{
     python -i ~/Scripts/script.py
}

It works perfectly from my home directory, but it cant find the directory ./Scripts/script.py if run from anywhere else.

The error message is:

/usr/local/Cellar/python/2.7.12/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't open file 'Projects/sym.py': [Errno 2] No such file or directory

Shouldn't the ~ initially direct to the home directory anyways?

Answer 1

From the error message:

/usr/local/Cellar/python/2.7.12/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't open file 'Projects/sym.py': [Errno 2] No such file or directory

you can see that your ~/Scripts/script.py tries to reference another file using a relative path Projects/sym.py.

Most likely you are calling the func function when your current directory is set to one that does not contain Projects/sym.py.

If your intention is to include a file from ~/Projects/sym.py you need to use an absolute path in the Python code or change the current directory to ~ inside the func prior to calling python.
