Introducing the 'if' statement [ID:983] (2/3)

in series: Python Beginners - the 'if' statement

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

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


# 2009-01-19 using Python 2.5
# The 'if' statement for Logic in Python
# Background:
# Indentend blocks: 
# Evaluating Boolean conditions

print "Please enter a number e.g. 22:",
n = int(raw_input())

# test for equality 
if n == 22:
    print "n is 22!"
    print "This is the indented block"    

# test for greater-than (and less-than)    
#if n > 22: # also try <
#    print "n is greater than 22"

# test not-equals-to    
#if n != 22:
#    print "n is NOT 22"
# single-equals is illegal, this will generate
# "SyntaxError: invalid syntax"
#if n = 40:
#    print "this syntax is legal in C!"

Excellent Website may consider paying for the membership

Nice! This the first time I know that adding a comma to the end of the print line won't make it go to a new line ;-)

Hey Ian,

I am slowly making my way through your videos. Until now they helped me out a lot.


Hi Ian,

I enjoyed your presentation, particularly how you dynamically magnified the text to draw attention to particular lines of code, and also how you used highlighting to really focus the viewer's attention. Very smoothly done, and not at all distracting.

Good job!

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
