How do I add a new line in a string in python?
Code examples in Python2 - Python3 is the same (just needs brackets on the print).a new line in a string is denoted by `\n` .. :>>> print "This is line one\nand this is line two"This is line oneand this is line twoto add a line to an existing string :>>> my_string = "This is line one">>> my_string = my_string + "\nandthis is line two"print my_stringThis is line oneand this is line twoYou can also use multiline syntax using the treble quote>>> my_string = """This is line one... and this is line two""">>> print my_stringThis is line oneand this is line twowhen you use the treble quote sytntax you don’t need to include the ‘\n’ and you can easily include indents etc and the string uses every single character within the string :>>> my_string = """This is line one... and this is line two""">>> print my_stringThis is line one and this is line two
How can I write HTML code as a JavaScript string?
Hiii friends,If you need to use html as a javascript string . I am providing you with a very easytechnique . There are a lot of techniques ,so we are going to see a few of them .by putting html tags with in inverted commas(“”)var a = “

How do I take two strings and add them to each other based off of their integer value equivalent?
It will only let me enter 1000 chars so ill post a few tiny pieces of it. Heres my constructor: public LetterInventory(String data) { String lowerCase = data.toLowerCase(); this.data = ""; for (int i = 0; i < lowerCase.length(); i++) { char j = lowerCase.charAt(i); if (Character.isLetter(j)) { size++; int k = j - 'a'; countLetters[k]++; data += j; } } } My add method. /* Constructs and returns a new LetterInventory object that represents the sum of this letter * inventory and the other given LetterInventory. The counts for each letter should be added * together. The two LetterInventory objects being added together (this and other) should not * be changed by this method */ public LetterInventory add(LetterInventory other) { LetterInventory addLetters = new LetterInventory(this.data + other); return addLetters; }
How to concatenate a string and an int in C++?

Help me solve my code grinder question?
Description In this exercise your function receives a list containing two strings and returns a new string that displays these two strings as a sentence. Remember to include a space. Function Name concat Parameters words : a list containing two string values Return Value a string that is the two strings of the list combined with a space between them.
How do I add two strings in Java using the "+" operator for runtime input?
Firstly, there's a slight difference in semantics. If a is null, then a.concat(b) throws a NullPointerException but a+=b will treat the original value of a as if it were null. Furthermore, the concat() method only accepts String values while the + operator will silently convert the argument to a String (using the toString() method for objects). So the concat() method is more strict in what it accepts.To look under the hood, write a simple class with a += b;public class Concat { String cat(String a, String b) { a += b; return a; }}Now disassemble with javap -c (included in the Sun JDK). You should see a listing including:java.lang.String cat(java.lang.String, java.lang.String); Code: 0: new #2; //class java/lang/StringBuilder 3: dup 4: invokespecial #3; //Method java/lang/StringBuilder."
With JavaScript, how do you add new words to a string?
I'm always trying to abstract the code I write, in order write less code in the future...Take a look at the following code, it uses the String.prototype.replace() method coupled with a new RegExp() to create an expression out of a variable. All of this is wrapped in a function that can be integrated into any project's code modules.function interpose( str, pattern, replace ) { return ( str || "" ).replace( new RegExp(pattern, "g"), replace );}console.log( // Your text [ "Welcome to our town", interpose( "Welcome to our town", "our", "our small" ) ]);console.log( // With a Regular Expression [ "Welcome to our town", interpose( "Welcome to our town", "(our)", "$1 small" ) ]);console.log( // With a Regular Expression [ "Welcome to our town", interpose( "Welcome to our town", "^", "You're NOT " ) ]);console.log( // An integrity test [ "", interpose( "", "", "the omega" ) ]);Running the code above will output the following:["Welcome to our town", "Welcome to our small town"]["Welcome to our town", "Welcome to our small town"]["Welcome to our town", "You're NOT Welcome to our town"]["", "the omega"]The only downside to this is that I've harcoded the global flag - which can easily be removed or even made to be part of the argument list.
Java: When we concatenate two strings using the "+" operator, will the resulting string be stored in the string literal pool or not?
In Short answer is "test" will be stored in String Pool.Why? check detail explanation below. There are two ways to construct a string: implicit construction by assigning a string literal 1.String strLiteral = "Java";If you create object using String literal syntax e.g. "Java", it may return an existing object from String pool (a cache of String object)if it's already exists. Otherwise it will create and put in string pool for future re-use.or explicitly creating a String object via the new operator and constructor. 2.String strObject = new String("Java");When you create String object using new() operator, it always create a new object in heap memory.It also will be added to the String constants pool. when you use + it will create new String Literal and concatenate those two string in newly created String Literal (because String are Immutable in JAVA)In your case.String te = "te";(added in String constants pool ) String st = new String("st");(crate new object in heap Plus added in String constants pool )) String test = te + st;(it will add another string "test" in String constants pool because String are Immutable in JAVA)
Write a code using C++ fragment that will use the “+” operator to append the string username to the string message and store it into?
the string message_buffer where the username is first bracketed by the strings “{[” and “]}”. The strings are defined as follows: string username = “Paul”; string message = “Please join our message group!”; string message_buffer; After executing your code fragment, message_buffer must contain the following string: {[Paul]}Please join our message group! Also: Write the code fragment that will use the above code to allow the program to prepend more user name and message into message buffer created in. string username2 = “Martha”; string message2 = “Wazzup!”; After executing the code fragment, message_buffer should contain the following string: {[Martha]}Wazzup!{[Paul]}Please join our message group!
