The '.' operator needs to convert it's operands to strings using str() function

[snoopyjc]

The perl '.' operator concatenates strings. In perl, variables of other types are automatically changed to strings. In python, you have to manually apply the str() function in order to do that. For example:

$message = "i is " . $i;
