Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

import requests
if __name__ == "__main__":
    response = requests.get("http://www.python.org")
    for header in response.headers.keys():
        print(header  + ":" + response.headers[header])

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

import requests
http_proxy = "http://<ip_address>:<port>"
proxy_dictionary = { "http" : http_proxy}
requests.get("http://example.org", proxies=proxy_dictionary)

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

$ pip install packagename

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."
