In python, in this part, you should write a for loop, updating the df_users dataframe. go through each user, and update their zip-code (column name zip), to safe harbour specifications: if the user is from a zip code for the which the "geographic subdivision" is less than equal to 2, change the zip code to 0otherwise, change the zip code to be only the first 3 numbers of the full zip cidedo all this re-writting the zip_code columns of the df_users dataframehints: this will be several lines of code, looping through the dataframe, getting each zip code, checking the geographic subdivision with the population in zip_dict, and settig the zip_code accordingly.
