Why does inspect return different line for class inheriting from superclass?

不羁的心 提交于 2019-12-05 09:37:07
While trying to figure out if a function is called with the @decorator syntax , we realized that inspect has a different behaviour when looking at a decorated class that inherits from a superclass. The following behaviour was found with CPython 3.6.2 under Windows 10. It was also reproduced in CPython 3.7.0 under Linux 64 bits. import inspect def decorate(f): lines = inspect.stack()[1].code_context print(f.__name__, lines) return f @decorate class Foo: pass @decorate class Bar(dict): pass Output Foo ['@decorate\n'] Bar ['class Bar(dict):\n'] Why does inheritance change the behaviour of inspect

I try to start simple nodejs server inside Docker container and debug it with chrome://inspect or WebStorm. Debugging port 9229 is binded but inspection not works.

Python: how does inspect.ismethod work?

核能气质少年 提交于 2019-12-05 02:46:14
I'm trying to get the name of all methods in my class. When testing how the inspect module works, i extraced one of my methods by obj = MyClass.__dict__['mymethodname'] . But now inspect.ismethod(obj) returns False while inspect.isfunction(obj) returns True , and i don't understand why. Is there some strange way of marking methods as methods that i am not aware of? I thought it was just that it is defined in the class and takes self as its first argument. atzz You are seeing some effects of the behind-the-scenes machinery of Python. When you write f = MyClass.__dict__['mymethodname'] , you get

How to inspect a variable on a JSP page

五迷三道 提交于 2019-12-04 22:57:59
I have a set of working pages and want to inspect variables at a break point on a JSP page. unfortunately the context menu for the variable doesn't show the normal Inspect/Watch options as it does when in a Java file. Any ideas? Martín C Here is a solution worked for me: In Eclipse open the Display tab view (Window -> Show View -> Display) In the Display tab write the variable or expression you want to inspect. Select it and do a right click and you'll have the a menu with the option inspect (or you can do a Ctrl + Shift + I), it will show you the value of the variable. Hope it helps!

问题 I've followed the instructions at google: https://developer.chrome.com/devtools/docs/remote-debugging. I've also went over the troubleshooting section - but nothing seems to work.

On windows 8 I run chrome (44.0.2388.0 canary). I've installed Samsung USB Driver, and my computer can see my device. I do not get any notification when

问题 I'm working with a winforms application that is targeting .net 4.5 and I really need to inspect the UI elements. I've used Snoop to inspect wpf elements in the past, and I've come across Hawekeye as well. However, it appears hawkeye is not compatible with .net 4.5. Are there any tools out there than can give me similar results? 回答1: Seems like the old tools no longer work like UI Spy either. Microsoft have an Inspect tool available here (Inspect tool). It's part of the Win8 SDK. I'm looking

Python: can a decorator determine if a function is being defined inside a class?

微笑、不失礼 提交于 2019-12-03 16:10:52
问题 I'm writing a decorator, and for various annoying reasons[0] it would be expedient to check if the function it is wrapping is being defined stand-alone or as part of a class (and further which classes that new class is subclassing). For example: def my_decorator(f): defined_in_class = ?? print "%r: %s" %(f, defined_in_class) @my_decorator def foo(): pass class Bar(object): @my_decorator def bar(self): pass Should print: <function foo …>: False <function bar …>: True Also, please note: At the

Python debugging: get filename and line number from which a function is called?

橙三吉。 提交于 2019-12-03 06:38:46
问题 I'm currently building quite a complex system in Python, and when I'm debugging I often put simple print statements in several scripts. To keep an overview I often also want to print out the file name and line number where the print statement is located. I can of course do that manually, or with something like this: from inspect import currentframe, getframeinfo print getframeinfo(currentframe()).filename + ':' + str(getframeinfo(currentframe()).lineno) + ' - ', 'what I actually want to print
