Importing modules within the same directory

Question

Consider the following directory structure:

lib/ markov.py solver.py test.py

markov.py has the following code: super() throwing an error in Sublime Text, works in PyCharm/Terminal

solver.py only contains a bunch of mathematical functions, here's an example of one:

def mm1_busy_idle(arrival, service): return round(1 - (arrival / service), 4)

Now, when I try to do import solver in markov.py, PyCharm tells me that there's No module named solver. However, when I do import test it does it just well and I can run the test function from there:

def test(): print("test!")

Also, when I hover over test.test() PyCharm shows me the following tooltip: Cannot find reference 'test' in '__init__.py'.

My question is: Why can I import test and run the function test() but I can't import solver in markov.py?

add one file (__init__.py empty file) in lib,

lib/ __init__.py markov.py solver.py test.py

An ultimate solution:

import sys sys.path.append("/path/to/lib")
