Some other articles Y111 - More on Collections and Sequences Mutable v Immuatble objects in Python, and the implication Accessing variables across subroutine boundaries - Perl, Python, Java and Tcl zip in Python Python for loops - applying a temporary second name to the same object List slices in Python - 2 and 3 values forms, with an uplifting example Python dictionaries - mutable and immutable keys and values Copying - duplicating data, or just adding a name? Perl and Python compared Sorting - naturally, or into a different order Sorting people by their names This article List Comprehensions in Python Anonymous functions (lambdas) and map in Python Callbacks - a more complex code sandwich Last elements in a Perl or Python list Python - extend v append on a list Copying a reference, or cloning What is a callback? Python is a fabulous language Y105 - Functions, Modules and Packages From and Import in Python - where is the module loaded from? Embedding more complex code into a named block Nesting decorators Recursion in Python - the classic example What are callbacks? Why use them? An example in Python What is the difference between a function and a method? Reading command line parameters in Python A good example of recursion - a real use in Python Python - even named code blocks are objects Multiple yields and no loops in a Python generator? Python functions - an introduction to how they work Python varables - checking existance, and call by name or by value? Exception, Lambda, Generator, Slice, Dict - examples in one Python program vargs in Python - how to call a method with unknown number of parameters Optional positional and named parameters in Python Default local - a good choice by the author of Python Static variables in Python? Python timing - when to use a list, and when to use a generator Functions are first class variables in Lua and Python Finding all the unique lines in a file, using Python or Perl Python Packages - groupings of modules. An introduction Static variables in functions - and better ways using objects Passing optional and named parameters to python methods Catching the fishes first? Passing parameters to Python functions - the options you have Returning multiple values from a function call in various languages - a comparison Using an exception to initialise a static variable in a Python function / method Python - some common questions answered in code examples Passing a variable number of parameters in to a function / method Program for reliability and efficiency - do not duplicate, but rather share and re-use Optional and named parameters to Python functions/methods This article Global and Enable - two misused words! Good example of recursion in Python - analyse an RSS feed Sample code with errors in it on our web site Optional parameters to Python functions Multiple returns from a function in Python Conversion of OSI grid references to Eastings and Northings Dynamic code - Python Optional and named parameters in Python What to do with a huge crop of apples Anonymous functions (lambdas) and map in Python Sharing variables with functions, but keeping them local too - Python Global - Tcl, PHP, Python Python Script - easy examples of lots of basics Returning multiple values from a function (Perl, PHP, Python) A better alternative to cutting and pasting code Function / method parameters with * and ** in Python It's the 1st, not the 1nd 1rd or 1th.
