It is easy to create clean bug-free programs in Python due to the motto: "Errors should never pass silently." Python is an [[wp:Interpreter (computing)|interpreter]]. Python source files (.py files) are typically compiled to an intermediate [[bytecode]] language (.pyc files) and executed by a Python Virtual Machine.

===Notes===

~~Note: because~~ Python uses whitespace for structure, do not format long code examples with leading whitespace, instead use <code><nowiki><pre></pre></nowiki></code> tags, or, preferably, <code><nowiki><lang python></lang></nowiki></code> tags. This will make it easier to copy code into and out of the wiki. Example:

This will make it easier to copy code into and out of the wiki. Example:

<lang python>print 'this line must not have leading indentation!'

:<lang python>print 'this line must not have leading indentation!'

if True:

print 'example: ', foo(3), len(bar)</lang>

Some Python examples may deviate from idiomatic Python because they may be written to work in Python 3.X as well as Python 2.X environments. This includes doing things like:

* Using brackets in print statements/functions of one expression.

* Using zip and not izip; keys(), values(), items() and not their iter- forms.

* Checking for raw_input and setting raw_input to input if not found.

* Conditionally importing reduce if it is not found.

This style is not a requirement for Python code on RC, but it may be in use and should not necessarily be 'corrected' if found in examples.
