Python: Find word in file and folders

Question

Problem: Using recursion it should go through all folders and files and search for a specific word. If you find a match then you should print path to file and line order is on. Finally, print out how many folders and files you have searched through and the number of times the word has appeared in the files.

I find this problem difficult and need some help. My code contain errors, but I am not sure how to solve these problems. Two of my errors: My solution does not count the occurrence of words correct, any tips? Pressing Search results in output in terminal, not in GUI-window.
