How to call a function using relative path from other place?

Question

I an writing a Python package. The index like bellow

main.py pkg |--utils.py |--files |--1.txt |--2.txt

I write a function to load the file 1.txt in the utils.py using relative path. And it works in the utils.py, but fail when I call the function in the main.py.

I konw the reason is the relative path has changed. I want to know how to solve it with not change the relative path.

Another problems is how to add the file to the python package when upload to the pipy.

I find a similiar question, stackoverflow.com/questions/4519127/… — imhuay

The best way to handle this is by assigning files/* as package_data and using pkg_resources.resource_filename. In your setup.py, assuming your package is named "pkg", add the following inside of setup():

package_data={'pkg': ['files/*']}

Then to use:

import pkg_resources filepath = pkg_resources.resource_filename('pkg', '1.txt')
