What does the backslash mean? I mean after the first set of double quotes, with the string in it, there is the backslash. What is that for?


print "Ah, so your name is %s, your quest is %s, " \
"and your favorite color is %s." % (name, quest, color)

Hi, @bytemaster94965 ,

In that statement, the \ is a line continuation character. Effectively, the two lines that you have are considered by the Python interpreter as one line of code, or one statement.

It is equivalent to ...

print "Ah, so your name is %s, your quest is %s, " "and your favorite color is %s." % (name, quest, color)

But the above combined line contains two strings with whitespace instead of an operator in between them. In such a situation, the Python interpreter concatenates them into one string.

Here it is again, with a + operator that explicitly concatenates the strings, at the same time that it distributes the statement again into two lines ...

print "Ah, so your name is %s, your quest is %s, " +
"and your favorite color is %s." % (name, quest, color)

So are you saying the '\' is the same as '+' and they both may not even be used to get the same output?

The \ just means that the current statement is to be continued onto the next line. In this particular case, the concatenation operator is not needed, because whitespace can be used to combine strings, but it could be placed there for clarity.
