76 | Knowing this we can create the correct XPath query and use the lxml
77 | ``xpath`` function like this:
78 |
79 | .. code-block:: python
80 |
81 | #This will create a list of buyers:
82 | buyers = tree.xpath('//div[@title="buyer-name"]/text()')
83 | #This will create a list of prices
84 | prices = tree.xpath('//span[@class="item-price"]/text()')
85 |
86 | Let's see what we got exactly:
87 |
88 | .. code-block:: python
89 |
90 | print('Buyers: ', buyers)
91 | print('Prices: ', prices)
92 |
93 | ::
94 |
95 | Buyers: ['Carson Busses', 'Earl E. Byrd', 'Patty Cakes',
96 | 'Derri Anne Connecticut', 'Moe Dess', 'Leda Doggslife', 'Dan Druff',
97 | 'Al Fresco', 'Ido Hoe', 'Howie Kisses', 'Len Lease', 'Phil Meup',
98 | 'Ira Pent', 'Ben D. Rules', 'Ave Sectomy', 'Gary Shattire',
99 | 'Bobbi Soks', 'Sheila Takya', 'Rose Tattoo', 'Moe Tell']

102 | '$13.99', '$31.57', '$8.49', '$14.47', '$15.86', '$11.11',
103 | '$15.98', '$16.27', '$7.50', '$50.85', '$14.26', '$5.68',

106 | Congratulations! We have successfully scraped all the data we wanted from
107 | a web page using lxml and Requests. We have it stored in memory as two
108 | lists. Now we can do all sorts of cool stuff with it: we can analyze it
109 | using Python or we can save it to a file and share it with the world.
110 |
111 | Some more cool ideas to think about are modifying this script to iterate
112 | through the rest of the pages of this example dataset, or rewriting this
113 | application to use threads for improved speed.

10 | This document describes how to install Python 3.6 or 3.8 on Ubuntu Linux machines.
11 |
12 | To see which version of Python 3 you have installed, open a command prompt and run
13 |
14 | .. code-block:: console
15 |
16 | $ python3 --version
17 |
18 | If you are using Ubuntu 16.10 or newer, then you can easily install Python 3.6 with the following commands::
19 |
20 | $ sudo apt-get update
21 | $ sudo apt-get install python3.6
22 |
23 | If you're using another version of Ubuntu (e.g. the latest LTS release) or you want to use a more current Python, we recommend using the `deadsnakes PPA
