An book to coach programming via hands-on, attention-grabbing examples which are worthwhile and fun!
Python is a brilliant programming language. It's unfastened, strong, more uncomplicated to learn than so much languages, and has extensions to be had to do nearly something you'll think automatically.
But how do you certainly use it? There are a whole lot assets in the market for studying Python, yet none of them are very functional or fascinating - as a substitute, they pass over every one thought one after the other, by no means tying something jointly, yet spending lots of time misplaced in technical language, discussing the twenty alternative ways to complete every one easy task...
I are looking to write an booklet that at last supplies a concise creation to every little thing you may truly are looking to do with Python.
We'll commence with a brief yet thorough evaluate of the entire fundamentals, so that you don't even desire any past adventure with programming. however the majority of the booklet might be spent increase instance code to unravel fascinating real-world problems.
Python is astounding for automating repetitive projects that may another way take you hours - for example, quick amassing info from the internet, or renaming thousands of records. a number of the subject matters that I'm making plans to cover:
Collecting info from webpages (web scraping)
Interacting with PDF records - examining facts, growing PDFs, editing pages, including passwords...
Interacting with Excel records (less performance in OS X)
Calling different outdoors courses from inside of Python
Files - read/write/modify, unzip, rename, flow, etc.
Basic video game development
Interacting with SQL databases (internal and ODBC connections)
GUI (Graphical person Interface) layout - developing easy point-and-click courses that any one can use
Any different issues that you simply, my backers, are so much in!
Update: by way of renowned call for, I'll be including net software development
