well in this tutorial we are going to make script that tracks bitcoin price every hour with web scraping technique

so first we are going to use this third-party libraries, make sure to download them before we start :

- requests

- beautifulsoup4

- lxml

well the first thing we'll need to do to scrape a web page is to download the page, we can download it using requests library

i am going to use this website, you can use any website you want

now we are going to use beautifulsoup to parse this document and extract the text from the <tag> we want,
to know tha tag you want to extract the text from it you can use inspect element in Firefox or chrome

and now i want to know the Price tag in html code

and that's all i want to know now we can parse this tag from the page we downloaded before using Beautifulsoup

in this code i  used lxml which is the parser we will use to parse the tag we want ! you can use html parser as well

and now if we print soup we can see the html code of the website

here's the result :

now after we have located the tag we want to parse using inspect element, we can easily parse it by this code :

so 'span' is the tag that contain the data we want ! and the class_ is the class of this tag :

and if we print price we'll get this :

After we have the tag, we can get the data by getting its text:

the output :

that all !

if we want to track bitcoin price every hour we will need to create a while loop that repeat this operation every hour:

While True means loop forever

you will need to import time library to use this code time.sleep()

and i set time.sleep(3200) which means 1 hour

so it's going to do this operation forever every hour

hope that was helpful <3
