Write a web scraping code snippet in Python and expose how to run it and get the right results in a xls format file or HTML table

I need to web scrape the phone numbers from Hotels in Lisbon from Google results, and organize them in an Excel sheet with two columns "Hotels" and "Phone Numbers" or in an HTML table. I need to know how it is done and so I can adapt the code to any situation, for example "restaurants addresses in London" organized in two columns "restaurant", "address", as given examples. I am a student with the daunting task of to elaborate an Excel database, with probably more than 100 000 records with several fields for enterprises in my area and the associated data, like e-mail, address, locality, phone number, e-mail and website.The data is dispersed, there isn't a unique site or database, from where I can extract the data. The project should be working and if further assistance is required to make it work should be disposable. If there is also a solution to gather data from google maps, based on the same logic it would be useful. Please keep in mind, that you are just teaching and saving time of a student. This is not an enterprise recruiting!
