[Tutor] Python Command Line Args (input) equivalent to Perl

[Edward WIJAYA]

Dear Tutor,

I am new to Python, and I like to
learn more about it. Since I am
used to Perl before, I would like
to know what is Python equivalent
of Perl code below:


$filename = $ARGV[0];
open (FILE,"$filename") || die "Can't Open $filename: $!\n";
while<FILE>{ #dealing with it per-lines
   #process something here
}


Please also kindly suggest any pointer/website
link, where I can find Perl-Python concordance,
especially to facilitate Perl conversion to Python.

Thanks so much for your time.
Hope to hear from you again.
