The actual result from this code is as follows: 256 256 257 257 == is == is 256: 256: 257: 257: True True True False The catch is that Python keeps an internal array of integer objects for all integers between -5 and 256; that's why it works for 256 but not for 257. You might wonder why anyone would ever want to use is instead of ==. There are multiple valid answers; depending on the case, one is correct and the other isn't. But performance can also be a very important consideration. The basic guideline is that when comparing Python singletons such as True, False, and None, always compare using is.
Generators will be discussed more thoroughly in Chapter 6, Generators and Coroutines – Infinity, One Step at a Time. Explicit is better than implicit Imports, arguments, and variable names are just some of the many cases where explicit code is far easier to read at the cost of a little bit more effort and/or verbosity when writing the code. Here is an example: from spam import * from eggs import * some_function() [ 17 ] Pythonic Syntax, Common Pitfalls, and Style Guide While this saves you some typing, it becomes quite difficult to see where some_function is defined.
Errors should never pass silently. Unless explicitly silenced. In the face of ambiguity, refuse the temptation to guess. There should be one-- and preferably only one --obvious way to do it. Although that way may not be obvious at first unless you're Dutch. Now is better than never. Although never is often better than *right* now. If the implementation is hard to explain, it's a bad idea. If the implementation is easy to explain, it may be a good idea. Namespaces are one honking great idea -- let's do more of those!
