Conventions
In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.
Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We can include other contexts through the use of the include
directive."
A block of code is set as follows:
import unittest class StockTest(unittest.TestCase): def test_price_of_a_new_stock_class_should_be_None(self): stock = Stock("GOOG") self.assertIsNone(stock.price) if __name__ == "__main__": unittest.main()
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
class Stock: LONG_TERM_TIMESPAN = 10 SHORT_TERM_TIMESPAN = 5
Any command-line input or output is written as follows:
python3 -m unittest discover
New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Select the Publish JUnit test result report checkbox and enter the location of the nose2 unit test XML file."
Note
Warnings or important notes appear in a box like this.
