Advantages of using Requests library to download web files are: One can easily download the web directories by iterating recursively through the website! This is a browser-independent method and much faster! One can simply scrape a web page to get all the file URLs on a webpage and hence, download all files in a single command- Execute the code passing the option -m memory_profiler to the python interpreter to load the memory_profiler module and print to stdout the line-by-line analysis. If the file name was example.py, this would result in: $ python -m memory_profiler example.py Output will follow: ajax android angular api button c++ class database date dom dynamic exception file function html http image input java javascript jquery json laravel list mysql object oop ph php phplaravel phpmysql phpphp post python sed select spring sql string text time url view windows wordpress With files this large, reading the data into pandas directly can be difficult (or impossible) due to memory constrictions, especially if you’re working on a prosumer computer. In this post, I describe a method that will help you when working with large CSV files in python.

I looked into the requests documentation and found a better way to do it. That way involved just fetching the headers of a url before actually downloading it. To restrict download by file size, StringIO — Read and write strings as files¶ This module implements a file-like class, StringIO, that reads and writes a string buffer (also known as memory files). See the description of file objects for operations (section File Objects). Python Software Foundation. The Python Software Foundation is a non-profit corporation.
