pythondev | help | Hi, I need to create GUI application that accepts all possible keyboard shortcuts including ones used by OS. Pyglet does exactly what I need (<https://pyglet.readthedocs.io/en/pyglet-1.3-maintenance/programming_guide/keyboard.html#keyboard-exclusivity>), but it's too low-level. Is it possible to implement similar behaviour with PyQt or other cross-platform framework with widget library richer than pyglet has? | 2019-03-05T01:56:47.564700 | Marinda | pythondev_help_Marinda_2019-03-05T01:56:47.564700 | 1,551,751,007.5647 | 12,125 |

pythondev | help | Hi, any input is appreciated:
I have a class with about 15 mandatory data fields. I want the caller to instantiate an object from this class, using a classmethod, which reads and parses an excel file (e.g., `instance.from_excel(filepath)`).
I don’t want the user to construct it like `obj = MyClass(15_different_args)`, since that would be quite tedious and the data can only be extracted from an excel file anyways. Would I just set the data fields to `None`, some default value, or don’t set them at all in the `__init__` ?
Maybe I am just thinking about this wrong.
Example:
```
class MyClass:
def __init__(self, arg_1, arg_2=0, ...):
self.arg_1 = arg_1
# or use
self.arg_2 = arg_2
# or use
self.arg_3 = None
@classmethod
def from_excel(cls, filepath):
# do something
return cls(*value_list)

`itertools.product(all_district_possibilities)` does not give me a combination of coordinates, I don't know why..

pythondev | help | Quoting from a great article on Event Collaboration Architecture by Martin Flowler:
>"Event cascades are good because something happens and as a result of a string of local logical event connections something indirect happens. Event cascades are bad because something happens and as a result of a string of local logical event connections something indirect happens. Event cascades usually look pretty obvious when they are described like this, but until you see them they can be very hard to spot. This is an area where *visualization systems* that can build a graph of event chains by querying meta-data from the systems themselves could be very handy."
Another one:
>"With Event Collaboration you don't know who is listening to the events until run-time - which in practice means you can only find the links between the components in configuration data - and there may be multiple areas of configuration data. As a result these interactions are hard to find, understand and debug. It is very helpful here to use *automated tools* that can display the configuration of components at run time so you can see what you have."
