Hands-On Reactive Programming with Python

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: "In the RxPY implementation, operators are methods of the Observable class."

A block of code is set as follows:

Observable.from_(...) .filter() .distinct() .take(20) .map(...)

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

argv.subscribe(    on_next=lambda i: print("on_next: {}".format(i)),    on_error=lambda e: print("on_error: {}".format(e)),    on_completed=lambda: print("on_completed"))
