Webdef infinite_sequence(): num = 0 while True: yield num num += 1 This code block is short and sweet. First, you initialize the variable num and start an infinite loop. Then, you immediately yield num so that you can capture the initial state. This mimics the action of range (). After yield, you increment num by 1.
