In this episode we are going to build out a project using python. If you are a python beginner this simple application will give you some good practice.
We will be using python to make requests and do webscraping on amazon.de. If you have difficulty following along, I highly recommend my python for beginners tutorial which will teach you all the basics of python in 1 hour.

@MarioOrtiz008 4 года назад

Instead of price[1:5] you could have used price[:-3]. That way, the actual length of the string doesn't matter. It will just remove the last 3 characters (decimals + € symbol)

@RickyC0626 4 года назад

Or you can do price[1:] to get all the characters after the currency symbol and cast it to float. The resulting value can also be used to calculate total price for a list of products

this was a great episode, thanks! i'm new here but appreciate the simplicity - almost would prefer you also show you googling the things you googled to FIND the packages you dl'd and imported. SOunds a little goofy, but really new people often ask how you knew what packages to use, and it's so helpful to show experienced people googling it.

@lolmeeky 2 года назад

thank you so much for this tutorial! some things dont currently work (since this video is a few years old now and Amazon has changed your ability to scrape from them, it seems), but I still learned the basics about web scraping from this! I changed up my program to also send price differences from other websites too. Even the parts about 2-factor verification were useful and now its something extra I know! Thanks again!

@walfranpinto80 4 года назад

im new to coding, mind explaining?

@psd.3144 4 года назад

@@walfranpinto80 it's just an infinite loop that will always run when the program gets to it. True is always true so it will never not run. You usually want some kind of limit on how much a loop can run, especially in something like the c language family. Python kinda saves you from bad memory management because it does a lot on it's own, but it is a convention not to do that if others are working with or going to use your code. Since this is more of a concept style of video tutorial, it isn't really an issue though.

@DontBeMadBro 4 года назад

just to point out, remember that price[0:5] will not be effective for smaller prices, in such a case, i would consider split this string by delimiter, which is dot and then save the first part of the outcome. This way script won't be dependent by different number of digits, nice tutorial!

@HaynesX 4 года назад

Why not just .replace() the comma and currency symbol with nothing and convert to float to get the exact price? Or is that very inefficient?

@ryankraft9897 5 лет назад

A friend and I developed something similar that tracked prices of over a million products from a large Chinese retailer. The goal was to predict trends in pricing (we actually found that many items followed a perfect sin curve leading to very predictable "ideal" purchase dates). Turns out price tracking large websites such as amazon (and the site we tracked) is against terms of service. You are not allowed to explicitly track and display old pricing of Amazon's products. So long story short, now my IP address is permanently banned from the site I was tracking.

@martingurasvili4091 5 лет назад

Theres a easier way to do it with any url, so add a url input , so you can C&P the link, then most sites make a new id for the discounted price so all you have to do is make an if statement to check if there is a discounted box, then follow the rest of his steps to send the email for example the regular price id for amazon is "priceblock_ourprice" and the discounted is "priceblock_dealprice" (i have been learning c++ and python for not that long so if i have made a mistake please correct me)

@advayiyer6456 5 лет назад
