Although such objects can be copied, in-place - changes support direct modification. - -So remember that when [copying](https://stackoverflow.com/questions/2612802/how-to-clone-or-copy-a-list#2612815) -or referencing a list. - -Also, [take care with handling mutables as arguments and as default arguments](http://www.thedigitalcatonline.com/blog/2015/02/11/default-arguments-in-python/), -also explained [here](https://docs.python.org/3/tutorial/controlflow.html#default-argument-values) and [here](https://docs.python-guide.org/writing/gotchas/) -(common gotchas). - -From [Scopes an Namespaces](https://docs.python.org/3/tutorial/classes.html#python-scopes-and-namespaces), telling that assignments bind names to objects: - - A special quirk of Python is that – if no global statement is in effect – - assignments to names always go into the innermost scope.

In fact, all operations that introduce new names use the local - scope: in particular, import statements and function definitions bind the - module or function name in the local scope. - - The global statement can be used to indicate that particular variables live in - the global scope and should be rebound there; the nonlocal statement indicates - that particular variables live in an enclosing scope and should be rebound - there. - - [...] - - Actually, you may have guessed the answer: the special thing about methods is - that the instance object is passed as the first argument of the function.

This lock is necessary mainly because CPython's memory - management is not thread-safe. (However, since the GIL exists, other features - have grown to depend on the guarantees that it enforces.) - - [...] - - The GIL is controversial because it prevents multithreaded CPython programs - from taking full advantage of multiprocessor systems in certain situations. - Note that potentially blocking or long-running operations, such as I/O, image - processing, and NumPy number crunching, happen outside the GIL. Therefore it is - only in multithreaded programs that spend a lot of time inside the GIL, - interpreting CPython bytecode, that the GIL becomes a bottleneck. - -From: [Thread State and the Global Interpreter Lock](https://docs.python.org/3/c-api/init.html#thread-state-and-the-global-interpreter-lock): - - When threads are created using the dedicated Python APIs (such as the threading - module), a thread state is automatically associated to them and the code showed - above is therefore correct. However, when threads are created from C (for - example by a third-party library with its own thread management), they don’t - hold the GIL, nor is there a thread state structure for them. - -### Nice stuff - -* [Verbose Regular Expressions](http://www.diveintopython3.net/regular-expressions.html#verbosere). - -## Implementations - -* [MicroPython - Python for microcontrollers](http://micropython.org/) ([compiling](https://github.com/micropython/micropython/wiki/Getting-Started). - -## Libraries and applications - -* QGIS. -* [SciPy.org — SciPy.org](https://www.scipy.org/) ([package](https://packages.debian.org/stable/python-scipy)). - -## Frameworks - -* [Welcome | Flask (A Python Microframework)](http://flask.pocoo.org/) ([package](https://packages.debian.org/stretch/python-flask)). -* Async: [asyncio](https://docs.python.org/3/library/asyncio.html), Twisted and Tornado. -* [Anaconda Data Science Platform](https://www.anaconda.com/). -* [Streamlit](https://streamlit.io). - -## IDEs - -* [PyCharm](https://www.jetbrains.com/pycharm/). - -## Misc - -* [Indentation](https://www.python.org/dev/peps/pep-0008/#indentation): Use 4 spaces per indentation level. - -## Test projects - -* [Arduino Blog » How close are we to doomsday?
