I'm back to working on my calculator again, and I decided to take a new approach using a loop to create buttons instead of writing every button.

How do I get Tk to execute a string of code following "command?" I've tried everything i've come up with.

for(0..9){
        $input=$_;
        $_ = $left_num -> Button(
         -text => "$input",
         -background => 'grey',
         -width => 5,
         -height => 2,
         -command => $number=$number==0||$equals!=0?$input:$number.$in
+put,
    ) -> pack();
}

Thanks in advance!
