In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "We added closeAccount to SpringBankView to let the customer close an existing account it its balance is zero."

A block of code is set as follows:

def get_article(self, article):
if article in self.cache:
return self.cache[article]
else:
return self.delegate.get_article(article)

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

def get_article(self, article):
if article in self.cache:
return self.cache[article]
else:
return self.delegate.get_article(article)

Any command-line input or output is written as follows:

$ svn checkout https://src.springframework.org/svn/se-springpython-py/trunk/springpython springpython

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Let's look at the layout of the gen-cherrypy-app plugin as an example."
