There's More Than One Way To Do It

When I started this blog, my intent was to illustrate different ways to do things in Perl (where TIMTOWTDI originated). Since then I have transitioned from Perl to Python, become active in several open source software projects, and started to learn how to contribute to project code in addition to test automation. I am returning to the blog to discuss things as I learn them. 'There's More Than One Way To Do It' remains true, even using different languages or an established design pattern.

there is more than one way to make sure a variable has a value

if (!$variable1) {
    $variable1 = 'default';
}

unless (defined($variable2)) {
    $variable2 = 'default';
}

can be done much more quickly as

$variable1 ||= 'default'; # true or
$variable2 //= 'default'; # defined or

i prefer the second
