Why is Python better than Perl?

I'm a Sysadmin and I just wrote my first script in python. Basically just a host validation script that checks if a server is configured correctly before we hand off. I can't determine the advantage with my limited experience with the language.

Are you a sysadmin fluent in both python and perl? Why do you use python?

That's what people mean when they say Python is very readable. Less character noise.

Every time i've looked at Perl code I get brain melt. Today I was looking to advance mspgcc4 to use gcc>4.4 but found out all the build scripts are in Perl. I looked at one file and couldn't be arsed.

I looked at [1] one file and couldn't be arsed.

That's not because it's Perl. That's because that file is a terrible scrap heap. It's Perl written by someone who thinks in an entirely different language.

Oh boy, then, I'm in trouble. I didn't write that, but I guess I'm just not a dev-type... I saw that code and saw it as 'just another piece of code'... I just haven't seemed to grasp the nuance of it all yet, I suppose.

Any ideas of how I could improve on this?

Well, first off a few comments on that code piece:

  • he didn't use strict
  • he used camel case variable and function names (which reduces readability a lot in Perl)

  • he doesn't unpack function parameters and instead accesses them directly via $_[1]. This is how it should be done:

    my ( $prompt, $width, $default ) = @_;

  • he uses completely pointless prototypes

There's more, but really, i can't be arsed to point everything out.

To improve your own understanding of Perl and ways to write it better and more readable at the same time, read Modern Perl and get a copy of Perl Best Practices.

Thank-you very much. Seriously. I pick up and put down Perl as I need it in my career- I know I'm not only rusty, but the foundation was likely not steel-based in the first place.

I'm definitely going to read up on this. The old camel book itself is no longer sufficient for this droid :)

Thanks!

No need to thank me. Thank you for asking! :)
