Real Python: An Introduction to Python Through Practical Examples
An publication to educate programming via hands-on, fascinating examples which are invaluable and fun!
Python is a brilliant programming language. It's loose, robust, more straightforward to learn than so much languages, and has extensions to be had to do virtually something you'll think automatically.
But how do you certainly use it? There are lots of assets in the market for studying Python, yet none of them are very sensible or fascinating - as a substitute, they pass over each one notion one after the other, by no means tying whatever jointly, yet spending lots of time misplaced in technical language, discussing the twenty alternative ways to complete each one simple job. ..
I are looking to write an ebook that eventually supplies a concise creation to every thing you may really are looking to do with Python.
We'll begin with a brief yet thorough review of all of the fundamentals, so that you don't even want any past event with programming. however the majority of the e-book may be spent increase instance code to resolve attention-grabbing real-world problems.
Python is astounding for automating repetitive initiatives that may in a different way take you hours - for example, quick amassing info from the net, or renaming thousands of documents. a number of the themes that I'm making plans to cover:
Collecting facts from webpages (web scraping)
Interacting with PDF records - examining info, developing PDFs, enhancing pages, including passwords. ..
Interacting with Excel documents (less performance in OS X)
Calling different outdoor courses from inside Python
Files - read/write/modify, unzip, rename, circulate, etc.
Basic online game development
Interacting with SQL databases (internal and ODBC connections)
GUI (Graphical person Interface) layout - growing uncomplicated point-and-click courses that any one can use
Any different subject matters that you simply, my backers, are so much in!
Update: via well known call for, I'll be including net program development

If maxsplit is given, at most maxsplit splits are done. If sep is not specified or is None, any whitespace string is a separator. split('*') yields ['a','b']. , ['a','*','b']). , list or tuple) of strings into a single string, with sep added between each item. join(['a','b']) yields 'a*b'). replace(old, new [, count]) Returns a copy of string s with all occurrences of substring old replaced by new. If count is passed, the first count oc- currences are replaced. join(x). splitlines([keepends]) Splits string s on line breaks, returning lines list.
