Python Beginners - the 'if' statement [ID:405]

a series of video-tutorials by Ian Ozsvald

This short series introduces logic in Python by showing you the 'if' statement. Logical control is fundamental to your control of Python programs, this series will quickly introduce you to the basics.

Video Tutorials

1. Overview (if)

Testing conditions is key to programming in any imperative programming language (e.g. Python, Java, C). We use the 'if' statement to decide on one course of action if the test is True or another course of action if the test is False. In this short series we use Python 2.5 to demonstrate 'if', 'else' and 'elif'.

2. Introducing the 'if' statement

Learn how the 'if' statement works in Python. In this episode we experiment with some simple logic tests using numbers and strings on True conditions. In the next episode we look at what happens if our condition is False using 'else' and 'elif'. Using: Python 2.5 on Windows, applies cross-platform Background: If, Then and Else: http://en.wikipedia.org/wiki/If-then-else Loops and iteration for i [...]

3. Using 'elif' and 'else'

Once you have an 'if' statement, you'll want to handle alternative flows of logic if your condition is False. 'else' lets us do 'something else' including start another 'if' statement. 'elif' is a contraction of 'else-if' and it lets us do combined 'else', 'if' tests in fewer characters. Watch how 'else' and 'elif' are used, after this you'll know all there is to know about the 'if' statement in [...]

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for Ian
