note that you never run fetch_housing_data() if it is expected to pull data and create the file

The url call is supposed to pull from the internet a data folder and save it to that folder and call it housing.csv. So perhaps the issue lies with the pulling from the internet part

[buran]

well, as I said, you never call it
so you need

fetch_housing_data()
housing = load_housing_data()
housing.head()

this way you will call the function and we will see if it works as expected and create the file

Thanks that worked. I was coping code directly from a text book which said it should work.
