Line 161:

Please avoid using irrelevant concepts in the examples. For example, the python example on this page was,

<sourcesyntaxhighlight lang="pycon">

>>> def my_square(val):

... """ the callback """

Line 178:

3 ** 2 = 9

4 ** 2 = 16

</syntaxhighlight>

</source>

Why should we assume that the reader knows

Line 186:

I have since changed the above to:

<sourcesyntaxhighlight lang="pycon">

>>> def get_square(val):

... """ the callback """

Line 196:

>>> caller(get_square, 5)

25

</syntaxhighlight>

</source>

'''Caveat''': The example is complex because it demonstrates how callbacks can be implemented to achieve some complex behaviour; however, the program written to demonstrate this still should not include ''unnecessary'' concepts and be as simplistic as possible.
