It shows how to use - Python, and even more importantly, how *not* to use Python. - - -Language Constructs You Should Not Use -====================================== - -While Python has relatively few gotchas compared to other languages, it still -has some constructs which are only useful in corner cases, or are plain -dangerous. - - -from module import \* ---------------------- - - -Inside Function Definitions -^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -``from module import *`` is *invalid* inside function definitions. While many -versions of Python do not check for the invalidity, it does not make it more -valid, no more than having a smart lawyer makes a man innocent. Do not use it -like that ever. Even in versions where it was accepted, it made the function -execution slower, because the compiler could not be certain which names are -local and which are global. In Python 2.1 this construct causes warnings, and -sometimes even errors. - - -At Module Level -^^^^^^^^^^^^^^^ - -While it is valid to use ``from module import *`` at module level it is usually -a bad idea. For one, this loses an important property Python otherwise has --- -you can know where each toplevel name is defined by a simple "search" function -in your favourite editor. You also open yourself to trouble in the future, if -some module grows additional functions or classes. - -One of the most awful question asked on the newsgroup is why this code:: - - f = open("www") - f.read() - -does not work. Of course, it works just fine (assuming you have a file called -"www".) But it does not work if somewhere in the module, the statement ``from -os import *`` is present. The :mod:`os` module has a function called -:func:`open` which returns an integer. While it is very useful, shadowing a -builtin is one of its least useful properties. - -Remember, you can never know for sure what names a module exports, so either -take what you need --- ``from module import name1, name2``, or keep them in the -module and access on a per-need basis --- ``import module; print(module.name)``. - - -When It Is Just Fine -^^^^^^^^^^^^^^^^^^^^ - -There are situations in which ``from module import *`` is just fine: - -* The interactive prompt. For example, ``from math import *`` makes Python an - amazing scientific calculator. - -* When extending a module in C with a module in Python. - -* When the module advertises itself as ``from import *`` safe. - - -from module import name1, name2 -------------------------------- - -This is a "don't" which is much weaker than the previous "don't"s but is still -something you should not do if you don't have good reasons to do that. The -reason it is usually bad idea is because you suddenly have an object which lives -in two separate namespaces. When the binding in one namespace changes, the -binding in the other will not, so there will be a discrepancy between them. This -happens when, for example, one module is reloaded, or changes the definition of -a function at runtime. - -Bad example:: - - # foo.py - a = 1 - - # bar.py - from foo import a - if something(): - a = 2 # danger: foo.a != a - -Good example:: - - # foo.py - a = 1 - - # bar.py - import foo - if something(): - foo.a = 2 - - -except: -------- - -Python has the ``except:`` clause, which catches all exceptions. Since *every* -error in Python raises an exception, using ``except:`` can make many -programming errors look like runtime problems, which hinders the debugging -process. - -The following code shows a great example of why this is bad:: - - try: - foo = opne("file") # misspelled "open" - except: - sys.exit("could not open file!") - -The second line triggers a :exc:`NameError`, which is caught by the except -clause. The program will exit, and the error message the program prints will -make you think the problem is the readability of ``"file"`` when in fact -the real error has nothing to do with ``"file"``. - -A better way to write the above is :: - - try: - foo = opne("file") - except IOError: - sys.exit("could not open file") - -When this is run, Python will produce a traceback showing the :exc:`NameError`, -and it will be immediately apparent what needs to be fixed. - -.. index:: bare except, except; bare - -Because ``except:`` catches *all* exceptions, including :exc:`SystemExit`, -:exc:`KeyboardInterrupt`, and :exc:`GeneratorExit` (which is not an error and -should not normally be caught by user code), using a bare ``except:`` is almost -never a good idea. In situations where you need to catch all "normal" errors, -such as in a framework that runs callbacks, you can catch the base class for -all normal exceptions, :exc:`Exception`. - - -Exceptions -========== - -Exceptions are a useful feature of Python. You should learn to raise them -whenever something unexpected occurs, and catch them only where you can do -something about them. - -The following is a very popular anti-idiom :: - - def get_status(file): - if not os.path.exists(file): - print("file not found") - sys.exit(1) - return open(file).readline() - -Consider the case where the file gets deleted between the time the call to -:func:`os.path.exists` is made and the time :func:`open` is called. In that -case the last line will raise an :exc:`IOError`. The same thing would happen -if *file* exists but has no read permission. Since testing this on a normal -machine on existent and non-existent files makes it seem bugless, the test -results will seem fine, and the code will get shipped. Later an unhandled -:exc:`IOError` (or perhaps some other :exc:`EnvironmentError`) escapes to the -user, who gets to watch the ugly traceback. - -Here is a somewhat better way to do it. :: - - def get_status(file): - try: - return open(file).readline() - except EnvironmentError as err: - print("Unable to open file: {}".format(err)) - sys.exit(1) - -In this version, *either* the file gets opened and the line is read (so it -works even on flaky NFS or SMB connections), or an error message is printed -that provides all the available information on why the open failed, and the -application is aborted. - -However, even this version of :func:`get_status` makes too many assumptions --- -that it will only be used in a short running script, and not, say, in a long -running server. Sure, the caller could do something like :: - - try: - status = get_status(log) - except SystemExit: - status = None - -But there is a better way. You should try to use as few ``except`` clauses in -your code as you can --- the ones you do use will usually be inside calls which -should always succeed, or a catch-all in a main function. - -So, an even better version of :func:`get_status()` is probably :: - - def get_status(file): - return open(file).readline() - -The caller can deal with the exception if it wants (for example, if it tries -several files in a loop), or just let the exception filter upwards to *its* -caller. - -But the last version still has a serious problem --- due to implementation -details in CPython, the file would not be closed when an exception is raised -until the exception handler finishes; and, worse, in other implementations -(e.g., Jython) it might not be closed at all regardless of whether or not -an exception is raised. - -The best version of this function uses the ``open()`` call as a context -manager, which will ensure that the file gets closed as soon as the -function returns:: - - def get_status(file): - with open(file) as fp: - return fp.readline() - - -Using the Batteries -=================== - -Every so often, people seem to be writing stuff in the Python library again, -usually poorly. While the occasional module has a poor interface, it is usually -much better to use the rich standard library and data types that come with -Python than inventing your own. - -A useful module very few people know about is :mod:`os.path`. It always has the -correct path arithmetic for your operating system, and will usually be much -better than whatever you come up with yourself. - -Compare:: - - # ugh! - return dir+"/"+file - # better - return os.path.join(dir, file) - -More useful functions in :mod:`os.path`: :func:`basename`, :func:`dirname` and -:func:`splitext`. - -There are also many useful built-in functions people seem not to be aware of -for some reason: :func:`min` and :func:`max` can find the minimum/maximum of -any sequence with comparable semantics, for example, yet many people write -their own :func:`max`/:func:`min`. Another highly useful function is -:func:`functools.reduce` which can be used to repeatly apply a binary -operation to a sequence, reducing it to a single value.
