The aim is to show how many people from each building can reach different building in radius of 150 meters (so i can find the density of the pedestrian routes).

Ok, thank you for the patiance.
I installed PyCharm for trying make some tests. 

I add in a project the .py file for the adjacency list.

That's the main from the debuger:

pydev debugger: process 8904 is connecting

Connected to pydev debugger (build 182.3684.100)
Traceback (most recent call last):
  File "C:\Program Files\JetBrains\PyCharm 2018.2\helpers\pydev\pydevd.py", line 1664, in <module>
    main()

    globals = debugger.run(setup['file'], None, None, is_module)

    from arcpy import AddField_management
ModuleNotFoundError: No module named 'arcpy'

May I found the following lines from the code?
