A block of code is set as follows:

import os
response = os.popen('ping -n 1 10.0.0.1')
for line in response.readlines():
    print line,

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

i = 1

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

python setup.py install
