Sample text

Therefore, if you have a string that contains single quotes, you can make your life easier by enclosing the string in double quotes, and vice versa if you’ve got strings with quotes that have been enclosed in single quotes. SQL, the language that is used to obtain data from databases, will often have single quoted strings inside of them that have nothing to do with Python. You can learn more about this when you reach Chapter 14. One more important rule to know is that by themselves, quotes will not let you create a newline in a string.

The reason is that the + operation relies on information contained in the actual items being added. Almost everything you use in Python can be thought of as an object with properties, and all of the 17 Chapter 2 properties combined define the object. One important property of every object is its type, and for now the important thing to understand about a type is that certain naturally understood things like the + operation work only when you perform them with two objects of compatible types. In most cases, besides numbers, compatible types should be thought of as the same type.

In case you wanted to print the literal string %d in your program, you achieve that in Python strings by using two % signs together. This is needed only when you also have valid format specifiers that you want Python to substitute for you in the same string: print “The %% behaves differently when combined with other letters, like this: %%d %%s %%f %d” % 10 The % behaves differently when combined with other letters, like this: %d %s %f 10 18 Numbers and Operators How It Works Note that Python pays attention to the combinations of letters and will behave correctly in a string that has both format specifiers as well as a double percent sign.
