In this paper, we describe a study that investigates the degree to which Python software developers are making the transition from Python 2 to Python 3. We have developed a Python compliance analyser, PyComply, and have analysed a previously studied corpus of Python applications called Qualitas. ...
from moviepy.editor import VideoFileClip src = VideoFileClip("t.mp4") w, h = src.size duration = src.duration def fl(gf, t): frame = gf(t) dh = int(h*t*3/duration) % h return np.vstack((frame[dh:], frame[:dh])) newclip = src.fl(fl, apply_to='mask') newclip.write_...
In case you need to port your project from Python 2 to Python 3, you might consider using such hook during the transition period.First:$ pip install pre-commitand then in your project's directory:$ pre-commit installNext, you need to add this entry to your .pre-commit-config.yaml- ...
If the pairing was good, then the processor’s own internal branch predication has a high likelihood of success, resulting in a nearly zero-overhead transition to the next opcode. A successful prediction saves a trip through the eval-loop including its unpredictable switch-case branch. Combined ...
Nowadays, many years after the python2->python3 transition, most software explicitly refers to python2 or python3 (at least on Linux). For example, they might call #!/usr/bin/env python2 or #!/usr/bin/env python3. This has for example (python-is-python3-package)...
A state diagram can help illustrate the transition between different states of Python3 functionality. Here is a simplified representation: SyntaxErrorsModuleImportIncorrectFunctionUsageVersionCompatibilityIssuesCorrectModifyCodeorUseVirtualEnvironment Conclusion ...
不过幸运的是NCL团队很贴心的给出了NCL向Python过渡的指导手册(NCL-to-Python Transition Guide),链接在文末。熟悉NCL的小伙伴借助官方的文档一定能很快的完成向python的过渡。 Linux配置环境 之前的文章里有详细介绍过如何安装conda,想看详情的请见:一文教你解决Python所有安装配置。下面简单介绍一下。
apply_to:apply_to表示变换过滤器fl是否需要同时作用于剪辑的音频和遮罩,其值可以为’mask’、‘audio’、[‘mask’,‘audio’] keep_duration:如果为True表示不改变剪辑的duration属性 实际上fl方法就是将参数fun作为make_frame方法,而fun本身带2个参数,剪辑的get_frame方法和时间t,而fun可以对剪辑自身的get_frame...
