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: "To summarize, we will implement a method called ParticleSimulator.evolve_numpy and benchmark it against the pure Python version, renamed as ParticleSimulator.evolve_python"
A block of code is set as follows:
def square(x):
return x * x
inputs = [0, 1, 2, 3, 4]
outputs = pool.map(square, inputs)
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 square(x):
return x * x
inputs = [0, 1, 2, 3, 4]
outputs = pool.map(square, inputs)
Any command-line input or output is written as follows:
$ time python -c 'import pi; pi.pi_serial()'
real 0m0.734s
user 0m0.731s
sys 0m0.004s
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: "On the right, clicking on the tab Callee Map will display a diagram of the function costs."
