Item 5: Write Helper Functions Instead of Complex Expressions(编写辅助函数,而不是复杂的表达式) Python简洁的语法使编写实现大量逻辑的单行表达式变得容易。 例如,假设我想解码来自URL的查询字符串。这里,每个查询字符串参数表示一个整数值: from urllib.parse import parse_qs my_values = parse_qs('red=5&blue...

您可能会想,“如果它如此容易理解,为什么不只使用png二进制掩码格式。”请记住,我们尝试制作COCO数据集的原因不是因为它是表示带注释的图像的最佳方式,而是因为其他所有人都在使用它。 前期准备: 安装pycocotools:Windows下安装- pip install git+https://github.com/philferriere/cocoapi.git#subdirectory=PythonAPI ...

For example, see the RPyc RPC library for Python (RPyc, 2009). The second way RMC can be achieved is through common middleware running on both client and server. The middleware can maintain a list of known public functions on a process, which may be remotely called from other processes. ...

On a side note, I'm happy to report that I now have access to both GROUPBY and PIVOTBY (after applying the September 10th update on the Current Channel), as well as eta-lambda for all of the lambda helper functions. Still waiting on the new regex functions and Python, but t...
In Python instead of applying map to 2D arrays one can use array broadcasting in 3D, e.g. arange(3)+arange(2)[:,None]+arange(3)[:,None,None] returns: [[[0, 1, 2], [1, 2, 3]], [[1, 2, 3], [2, 3, 4]],
