python PyQT qt 4.8 GUI library tutorial

shared by Benjamin Bandt-Horn on 14 Jan 14 - No Cached
  • a much better way to write GUI apps in Python is to use Trolltech's QT Designer to WYSIWYG-ly create a nice-looking interface, and then automatically generate the necessary code for it with pyuic (which is a UI compiler for QT that comes with the PyQT package.)

test interactive python examples documentation doctest

shared by Benjamin Bandt-Horn on 19 Dec 13 - No Cached
  • common ways to use doctest: To check that a module’s docstrings are up-to-date by verifying that all interactive examples still work as documented. To perform regression testing by verifying that interactive examples from a test file or a test object work as expected. To write tutorial documentation for a package, liberally illustrated with input-output examples. Depending on whether the examples or the expository text are emphasized, this has the flavor of “literate testing” or “executable documentation”.
  • Running the module as a script causes the examples in the docstrings to get executed and verified
  • The file content is treated as if it were a single giant docstring; the file doesn’t need to contain a Python program! For example, perhaps example.txt contains this
  • ...8 more annotations...
  • You can instruct the Python interpreter to run the doctest module directly from the standard library and pass the file name(s) on the command line:
  • if M.__test__ exists and “is true”, it must be a dict, and each entry maps a (string) name to a function object, class object, or string
  • Which Docstrings Are Examined?
  • Any expected output must immediately follow the final '>>> ' or '... ' line containing the code, and the expected output (if any) extends to the next '>>> ' or all-whitespace line.
  • Execution Context?
  • Directives
  • Whitespace is not allowed between the + or - and the directive option name. The directive option name can be any of the option flag names explained above
  • Unittest

python embedding Boost

shared by Benjamin Bandt-Horn on 14 Jan 14 - No Cached
  • The Boost Python Library is a framework for interfacing Python and C++. It allows you to quickly and seamlessly expose C++ classes functions and objects to Python, and vice-versa, using no special tools -- just your C++ compiler. It is designed to wrap C++ interfaces non-intrusively, so that you should not have to change the C++ code at all in order to wrap it, making Boost.Python ideal for exposing 3rd-party libraries to Python. The library's use of advanced metaprogramming techniques simplifies its syntax for users, so that wrapping code takes on the look of a kind of declarative interface definition language (IDL).

  • *name must occur before **name.
  • keys = sorted(keywords.keys()) for kw in keys: print kw, ":", keywords[kw]
  • Note that the list of keyword argument names is created by sorting the result of the keywords dictionary’s keys() method before printing its contents; if this is not done, the order in which the arguments are printed is undefined
  • ...11 more annotations...
  • They are syntactically restricted to a single expression
  • Like nested function definitions, lambda functions can reference variables from the containing scope
  • Coding Style
  • CamelCase for classes
  • lower_case_with_underscores for functions and methods
  • Always use self as the name for the first method argument
  • comments
  • docstrings
  • separate
  • 79 characters
  • 4-space indentation, and no tabs

    Python knows a number of compound data types, used to group together other values. The most versatile is the list, which can be written as a list of comma-separated values (items) between square brackets. List items need not all have the same type.
