I'm leaving Perl, traded it for Python. Some shortcuts I'd like to remember
Print out the contents of $variable in a structured format.
use Data::Dumper;
print Dumper($variable);
- $var += <value>
- Add <value> to $var (works for -, *, / too)
- $string .= $addstring
- Concatenate $string and $addstring
- $string = s/<regexp>/<newvalue>/[g]
- Substitute <regexp> with <newvalue> in $string. The g modifier makes the all occurrences of <regexp> are substituted.
