I must be missing something simple because I can't find a way to break 
out of a nested loop in Python.

Is there a way to label loops?

For the record, here's a Perl script of mine I'm trying to port...there 
may be 'malformed' lines in a TSV file I'm parsing that are better 
discarded than fixed.

my $ctr = 0;
OUTER:
while($line = <FILE>) {

     $ctr++;
     if ($ctr < 5) {next;}

     my @allVals  = split /\t/,$line;

     my $newline;
     foreach my $i (0..$#allVals) {

	if ($i == 0) {
	    if ($allVals[0] =~ /[^[:print:]]/) {next OUTER;}

	    $newline =  $allVals[0];
	}

	if (defined $headers{$i}) {

	    #if column not a number, skip line
	    if ($allVals[$i+1] !~ /^\d+$/) {next OUTER;}

	    $newline .= "\t".$allVals[$i+1];
	}
     }
     print $newline."\n";

}
