in series: Python Beginners - Functions

(Showmedo is undergoing major changes. To report any problems viewing the videos please email us and include browser and OS specifics. Cheers - Kyran.)

Building your code one line at a time at the command line is a common development approach. Here we build a simple piece of code and then build it into a function, adding features one step at a time.

This is the easiest way to approach building larger functions from simple ideas.

def create_hello():
    """create a greeting string with caller's name and age."""
    # first we'll make it print the hello
    # then we'll make it return a new string
    pass # TODO

name = 'ian'
age = 32
print "Hello %s, you are %d years old." % (name, age)

For a complete beginner to programming, maybe you could explain why you need to put 'results', then return it, then capture it again, when 'print' did the same thing. I'm sure its useful later on, but it makes no sense as of now. Even so, I still think your videos are the best.


is there supposed to be sound with this? I didn't hear anything.

the time spent on resizing windows is distracting.


I've been watching this beginners python series and have been enjoying it immensely. Thanks for an easy way to watch and learn a programming language. This is great!


Ian making functions easy thanks man!

-mark


great... thank you!


Ian,

Could you please clarify how you insert the arguments into the print string?

Is there a showmedo that highlights the use of %s and %d?

Where can I read more about this?

Thank you.


great episode, as always.

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
