Importing from sub-folder hierarchy in python
===

i am trying to import specified modules from test_file hierarchy 

something like :

    test_case1.py
    test_subsuite_2
    test_sub_2.1.1.py
    test_suite2

is it possible to do a run import on this hierarchy 
    
    

    /project/main.py
    /project/test_files

test_files folder hierarchy is like this :
    
    test_files
        test_suite1
            test_case1.py
            test_subsuite_1
                test_sub1_1.py
                test_sub1_2.py
            test_subsuite_2
                test_subsuite_2_1
                    test_sub_2.1.1.py
                test_sub2_1.py
                test_sub3_2.py
        
        test_suite2
            test_case2.py
            test_subsuite2_1
                test_sub21_1.py
                test_sub21_2.py
            test_subsuite2_2
                test_sub22_1.py
                test_sub23_2.py
