Hi @Yuvraj102 ,

Thanks for your feedback. That's just the URL's root directory (the full URL was too long to fit on a single line). The full URL is defined like this:

DOWNLOAD_ROOT = "https://raw.githubusercontent.com/ageron/handson-ml2/master/"
[...]
HOUSING_URL = DOWNLOAD_ROOT + "datasets/housing/housing.tgz"

So the full URL is: https://raw.githubusercontent.com/ageron/handson-ml2/master/datasets/housing/housing.tgz

If you run the whole code, it should work fine. The point of this paragraph is to explain that you don't need to download things manually, you can write functions that do it for you. This becomes useful if you need to download the data multiple times, e.g., on multiple different machines, or on different dates (to get updated data).

Hope this helps
