Re: Is this correct behavior for default parameters?

Bruce Pearson wrote:
The first call to test has the file_list empty but on the second call to
test the file_list is no longer empty but contains the values appended
in the first call.

Is this correct behavior? I'm using python 2.5
yes:

http://docs.python.org/ref/function.html

"Default parameter values are evaluated when the function
definition is executed." (in bold, even)

it's also explained in the tutorial (section 4.7.1) and in the FAQ.

(it's always a good idea to double-check the documentation or google a
little before convincing yourself that you may have found a bug in a
commonly used part of a system that's over 15 years old and has been
used by hundred of thousands of programmers).
