Online Tools

  • Pythontutor: VISUALIZE the execution of Python, Java, JavaScript, and TypeScript code !!!

    Online Python Tutor is a free educational tool created by Philip Guo !!! that helps students overcome a fundamental barrier to learning programming: understanding what happens as the computer executes each line of a program’s source code.

    Using this tool, a teacher or student can write Python, Java, JavaScript, and TypeScript programs in the Web browser and visualize what the computer is doing step-by-step as it executes those programs.

    Over one million people in over 165 countries have used Online Python Tutor to understand and debug their programs, often as a supplement to textbooks, lecture notes, and online programming tutorials.

‘is last’ for iterator

  • James Bowman: http://www.excamera.com/sphinx/article-islast.html

    islast: handling the last element of an iterator

    Doing something special for the last element of an iterator is a fairly common pattern. I needed it for the Python Jtag tools, so made this small wrapper …

    def islast(o):
       it = o.__iter__()
       e = it.next()
       while True:
          try:
             nxt = it.next()
             yield (False, e)
             e = nxt
          except StopIteration:
             yield (True, e)
             break
    
    # example
    # for i in islast(range(4)): print i
    

Web Frameworks

  • Tornado Web Server

    Tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed. By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user.
