Python download csv file from url requests

Below is the implementation resulting in iterating over a csv. Converting a response object into an iterator is as simple as using the splitlines method. Python offers several ways to download a file. In any case, the resulting textual data can be parsed—directly from memory—to be used rather than first saving to local storage. This can often be a more efficient approach in cases where temporary file use is preferred and remote files are not excessive in size.

To restrict download by file size, we can get the filesize from the Content-Length header and then do suitable comparisons. We can parse the url to get the filename. 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.
