问题 I'd like to print every line of python script as it's being executed, as well as the log from the console as every line is being executed. For example, for this script: import time print 'hello' time.sleep(3) print 'goodbye' I'd like it to generate the following in the console: line 1: import time line 2: print 'hello' hello line 3: time.sleep(3) line 4: print 'goodbye' goodbye See below for my attempt import subprocess as subp python_string = """ import sys import inspect class SetTrace

问题 I need to upload a local file to Google Cloud Storage using Scala language. What is the easiest way to do it? This file will also need to be public downloaded later. 回答1: Use the java library provided by Google. It will work with scala as well. They provide an example of how to use this library here. It's in java but the scala equivalent should be easy to code. 来源： https://stackoverflow.com/questions/25540158/how-to-easily-send-local-file-to-google-cloud-storage-in-scala

问题 I have been searching for a Kivy solution to capture the Android device rotation from one orientation to another. I have tried both of the window methods below but neither executes the on_rotate or rotate_screen routines when I rotate the device. I see there is an onConfigurationChanged event in java but I can't find the same event handling for Kivy. Window.on_rotate(self.on_rotate) Window.bind(on_rotate=self.rotate_screen) What I do get in the logcat is the following messages indicating the

问题 i'm new to MOXy and JaxB in general and I'm facing a problem with java.util.Date conversion. I'm unmarshaling an XML file (which I have no control of) to objects using a mapping file (I can neither manually annotate existing classes nor change them). My XML mapping file looks like this : <?xml version="1.0"?> <xml-bindings xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm" version="2.1"> <java-types> <java-type name="Observation"> <xml-type prop-order="date theoricalTime ci ch cr

问题 The execution of this script: tmp.js, that contains: var parameters = {}; (1,eval)("var parameters = {a:1}"); (1,eval)(console.log(parameters)); node tmp.js produces: {} If we comment out the first statement, and execute again the script, we obtain: { a: 1 } The global scope contains exactly the same variables with the same value, so why console.log displays a different value? 回答1: Because all code you run in Node is running in a Node module,¹ with its own scope, not at global scope. But the

问题 The CompositionTarget.Rendering event is the perfect thing to build a game's main loop upon. It basically fires at the rate of vsync (usually 60 Hz). Occurs just before the objects in the composition tree are rendered. The Rendering event is routed to the specified event handler after animation and layout have been applied to the composition tree. The per-frame animation how-to article explains a little bit more. Note that your event handler method is called after layout has been computed.

问题 I added two handlers with different formatters to my logger. The first one requires subclassing logging.Formatter to do custom formatting. The default formatter will suffice for the second handler. Let's say the first formatter simply removes newline characters from the message. The following script illustrates what seems like strange behavior: import logging logger = logging.getLogger(__name__) class CustomFormatter(logging.Formatter): def __init__(self, *args, **kwargs): super().__init__(
