Learn Python by Building Data Science Applications

Starting to code

Let's try to put into practice everything we've learned so far in code.

First, our request will go to a specific URL. It makes sense to store that URL as a variable:

base_url = 'https://nominatim.openstreetmap.org/search?'

Nominatim requires us to add at least two parameters:

• format: This will define the format of the data we'll get in return.

Due to the way requests work, we need to store those parameters in a dictionary:

params = { 'format':'json', 'q': 'Eiffel Tower'}

Finally, as we have everything we need now, we can send our request and get the answer. In the following snippet, we import the library and pass a GET request (using the  ...
