It is a file for the Historical Prices. When I ran the code, I was expecting it to start the download and put it into my downloads folder, but it doesn't do anything. It runs and then stops. No csv file shows up in my downloads.
So I think I'm missing something else in this code. You can do this with just urllib. It is one of the most popular Python packages for this purpose.
If you think about it for a bit, you may realize that connecting to a webpage on the web is practically the same as downloading its contents.
By the same logic, if there is a file we wish to download, we can make a GET request to it, catch the response and then export that response to a local file on our machine… Which is practically downloading the file.
Yes, it is that easy. It returns the file as a Python object. This way, we store it in a variable. The second one is more interesting. It specifies the mode in which we open the file. This will be give the filename in some cases correctly. However, there are times when the filename information is not present in the url. In that case, the Content-Disposition header will contain the filename information. Here is how to fetch it. The url-parsing code in conjuction with the above method to get filename from Content-Disposition header will work for most of the cases.
Use them and test the results. These are my 2 cents on downloading files using requests in Python. Let me know of other tricks I might have overlooked. This article was first posted on my personal blog. Especially if the files are big.
That is good idea and using with as a context manager is more better and looks great. THIS should be the correct answer! A small caveat for using. Mentioned in the docs here: docs.

That memory bloat sucks, maybe f. That's what's causing the memory bloat. Show 1 more comment. Ben Moskovitch Ben Moskovitch 1 1 silver badge 3 3 bronze badges. Here is a snippet import wget wget.
