Instead of downloading the pages, let’s just write the links out 4:40:41 PM In the last task we downloaded images directly to our machine into a folder in the current working directory. Since I am well acquainted with downloading files using requests, I decided to just write out the links into a text file instead […]
So you want to download images without a browser.. challenge accepted 3:43:41 PM [sourcecode language=”python”] #Image Site Downloader #USAGE: python igmurdownloader.py <category> <limit> import sys, requests, os, logging, bs4, re logging.basicConfig(level=logging.DEBUG, format="%(asctime)s – %(levelname)s – %(message)s") logging.disable(logging.CRITICAL) if len(sys.argv) == 3: logging.info("Command line argument 3") #TODO: get category, and limit category = sys.argv[1] limit = […]
Downloading a comic…. 9% 12:39:32 PM There is a solution provided in the book but this is my way of going around the task #comic saver – saves each post of a comic page #USAGE python comic.py import logging, requests, bs4, os, sys logging.basicConfig(level=logging.DEBUG, format=” %(asctime)s – %(levelname)s – %(message)s”) #TODO: get url if len( […]
How to fill in the gaps 1:49:09 AM I need help with this! I like this exercise but I cannot seem to find its ideal solution. Could someone suggest in pseudocode, please..? # finds files with a give prefix in a folder # locates any gaps in the numbering # renames all the later files to […]
Personally, one of the simplest projects yet This code (when properly indented) helps to list out all files with a size greater than the given limit. # Usage python big.py limit in MB import sys import os if len(sys.argv) >= 2: limit = sys.argv[1] if len(sys.argv) == 3: source = sys.argv[2] else: source = […]
As usual… super simple automation.. I know it is quite trivial, but the fact that with a few lines of code I could re-organize my files based on their extensions makes coding really fun even outside of work. Code # selective copy # walks through a folder tree and searches for files with a certain […]
Just my solution to the project I found the solution to the project provided in the book really good, but it zipped the entire folder structure in the absolute path. Something I am not pleased with. By adding the filepath base name to the zipfile.Zipfile.write() function, after the absolute file path (of the file to […]
With this script we can make a new directory and move files with a given ending into the directory. This was not a task in the book, but just something I thought of solving. Quite interesting to know what you could do with string operations like “startWith” and “endWith”. # creates new directory and moves […]
Searching through a list of text files in a given directory … I personally found this enjoyable. It was easier to solve compared to last problem. What I can say at this stage is, learn how to search to documentation and google! It helps… heheh.. oh yea, leave your suggestions in the comment box. see […]
Creating MadLib: It was quite a task to solve this problem but worth it. I learned how to retrieve command line arguments using sys module, regex to match and search for the keyword in a given string, and os to create new files and open files. I think a step further would be to […]

If you came all the way from part 1, you should get the book: Functional JavaScript In the last post, we learned about Closures and Scopes. Today, we are addressing Higher Order Functions – Let’s do this! Higher Order Function A first-class function takes a function as an argument returns a function as a result […]
Remember the Book: Functional JavaScript So chapter 3 right?…hm Scopes From my understanding, where a variable lives, while the extent of a scope means how long a variable holds a value. Global Scope This has the longest lifespan when you declare a variable without the var, you are defining a global variable (accessible to […]
Hey!! you missed me ? no..okay .. so chapter 2 First Class Functions According to the author, I quote, “the term first class means that soething is just a value. Is one that can go anywhere that any other value can go”. Therefore a first class function is as shown below: var number = function(){return […]
In my most recent Coding Blog Post I briefed on what I learned while reading the Book “DOM Enlightment“. The book improved my knowledge of DOM transversing, specific and list selection, style manipulation etc. This time I have decided on reading the book “Functional JavaScript” by Michael Fogus. I hope to prevent redundancy in my […]
Hope you found the part 1 helpful.. Okay, let’s begin… Styling style property to access a specific style property e.g. border-width, use selection.style.borderWidth or for background-color backgroundColor. getProperty, setProperty, removeProperty methods get – takes in only one argument; returns the value of that property e.g. selection.getProperty(“background-color”) set – updates the value of a specific property; […]
Part 2 is up! So I am at the moment reading the book “DOM Enlightment“, a really good book, and I thought to myself “Hmm.. why dont you blog about what you are learning form this book?”. So yea, hope you can get something out of this. Remember this, HTML is a tree made up […]
Scope the life-time of a variable; Global scope – variables declared without a (var) are in the global scope. Their life time is the longest. They are also easy to mutate at any time, thus you should take extra care when declaring variables in the global scope. Lexical scope – defines the visibility of the […]
