Scala uses Java strings (java.lang.String), so its string concatenation is the same as Java’s: the same thing is taking place in both. (The runtime is the same, after all.) There is a special StringBuilder class in Scala, that “provides an API compatible with java.lang.StringBuilder“; see http://www.scala-lang.org/api/2.7.5/scala/StringBuilder.html. But in terms of “best practices”, I think most … Read more
I’m guessing that you meant to do this: msg[‘Subject’] = “Auto Hella Restart Report ” + sys.argv[1] # To concatenate strings in Python, use ^
How about this: var=”${var}string”
Try doing this, there’s no special character to concatenate in bash : mystring=”${arg1}12${arg2}endoffile” explanations If you don’t put brackets, you will ask bash to concatenate $arg112 + $argendoffile (I guess that’s not what you asked) like in the following example : mystring=”$arg112$arg2endoffile” The brackets are delimiters for the variables when needed. When not needed, you … Read more
Keyword variable interpolation: $value = “${one}${two}” Source: http://docs.puppetlabs.com/puppet/4.3/reference/lang_variables.html#interpolation Note that although it might work without the curly braces, you should always use them.
You see this behavior as a result of the combination of operator precedence and string conversion. JLS 15.18.1 states: If only one operand expression is of type String, then string conversion (ยง5.1.11) is performed on the other operand to produce a string at run time. Therefore the right hand operands in your first expression are … Read more
You can escape by doubling the quotes g=”abcd “”” & a & “””” or write an explicit chr() call g=”abcd ” & chr(34) & a & chr(34)
Microsoft’s preference is for VB programmers to use & for strings and not +. You can also use the + operator to concatenate strings. However, to eliminate ambiguity, you should use the & operator instead.
Just use . for concatenating. And you missed out the $personCount increment! while ($personCount < 10) { $result .= $personCount . ‘ people’; $personCount++; } echo $result;
