It is too simplistic to provide accurate answers and contains some logical errors that need fixing. In order to generate more accurate answers, you need to know how to compare values and specify different courses of action based on the results. The code construction that allows us to do this is called a conditional statement. Conditional statements transform the script from being just a list of instructions to something that can make decisions on the fly based on the information that it receives.
32 CHAPTER 3 ■ VARIABLES AND DATA TYPES ■ Note The backslash \ escapes the new-line character, which means it tells the interpreter to ignore any special meaning that the next character might have. All the unescaped characters after that are treated normally. A value created using text in quotes will be given the type str (string). Nesting Quotes Sometimes, you will want to include literal quotation marks within your text. It is possible to nest quotes. That is, have one set of quotation marks inside another, so long as you use a different sort of quotation mark, like this: >>> text = "She quoted 'the rules' at him" In this instance, the interpreter will assume that it has reached the end of the text when it hits the second double quote ", so the substring 'the rules' is considered to be part of the main string including the single quotes.
