Here we start by looking at the simplest Hello World function in Python.
Note that the naming convention is for lowercase and underscores and that docstrings are recommended. Python functions are 'first class' (see wikipedia link below), this means that we can assign them to variables and pass them around - you may not have seen this if you come from a C++/Java background.
# Functions 1 using Python 2.5
"""print Hello! to the screen."""
# note 4 space indentation
# note naming convention with underscores
"""Function names should be lowercase, with words separated
by underscores as necessary to improve readability.
mixedCase is allowed only in contexts where that's already
the prevailing style (e.g. threading.py), to retain
# generally you always want a docstring as the first line(s)
# of a function using triple-quote strings (multiline)
# call hello_world function
# note that hello_world is a first-class function
#print "Python supports first-class functions"
#b = hello_world
Are you learning Python? To keep the site running clean and ad-free we've started Club ShowMeDo. The club will allow you access to some special videos we're making to pass on programming skills we consider important to the development and enjoyment of Free Open Source Software (FOSS).
The focus at the moment is on developing with the Python programming language, one of the backbones of the FOSS movement with a huge number of included and third-party libraries.
We welcome feedback and we want to hear your ideas.
Showmedo's development is fairly rapid and bugs will inevitably creep in. If you have any problems please drop us a line using the contact address below. Likewise, any suggestions for improvements to the site are gratefully received.
