Conventions used

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

Code in text: 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: “The server is built using Flask, while the client leverages Python’s asyncio library for asynchronous operations.”

A block of code is set as follows:

def busy_wait(duration):
    current_time = time.time()
    while (time.time() < current_time + duration):
        pass

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

@app.route("/")
def welcome():
    return "<p>Welcome to our Fitness Evaluation Server!</p>"

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

pip install Flask

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Clicking on the function’s name will bring us to the Function overview screen.”
