Wrong report in Jaseci Builtin str actions

[TharukaCkasthuri]

.str::is_alnum is to Return true if the string is alpha numerical. but this action returns true only if the string only contains numerical values.

Ex:

walker init{
    _string = "123 Hello World";
    report _string.str::is_alnum;
}

This reports false.

But

walker init{
    _string = "123";
    report _string.str::is_alnum;
}

this reports true.

I believe that this is the correct behavior for .str::is_alnum.

In your first example:

walker init{
    _string = "123 Hello World";
    report _string.str::is_alnum;
}

This reports False because the string "123 Hello World" is not alphanumeric as it has space characters " " that are not numerals or letters.

If you were to replace the whitespace from the string first:

walker init{
    _string = "123 Hello World";
    _string = _string.str::replace(" ", "");
   report _string;
   report _string.is_alnum;
}

This reports "123HelloWorld", True
