WPS 最近被另一家软件公司 Altair 收购了，这个公司应该也是看到了这个场景的价值，既能保证使用 SAS 语言构建的历史模型平稳运行，又可以更高效地帮助公司向开源+闭源混合语言体系结构过渡，且能以更低的成本，保留和利用闭源软件+闭源语言的最大优势。参考资料[1] r-vs-python-vs-sas: https://medium.com/@ak...
sasoptpy is the Python interface for SAS Optimization and SAS/OR solvers. It enables developers to quickly formulate and solve mathematical optimization problems by using native Python data structures. sasoptpy works with both client-side and server-side data, and it allows concurrency, making it...
The SAS Scripting Wrapper for Analytics Transfer (SWAT) package is the Python client to SAS Cloud Analytic Services (CAS). It allows users to execute CAS actions and process the results all from Python. - sassoftware/python-swat
pandas支持读取和输出多种数据类型,包括但不限于csv、txt、xlsx、json、html、sql、parquet、sas、spss、stata、hdf5 读取一般通过read_*函数实现,输出通过to_*函数实现。 3. 选择数据子集 导入数据后,一般要对数据进行清洗,我们会选择部分数据使用,也就是子集。 在pandas中选择数据子集非常简单,通过筛选行和列字段...

You either need a connection string with SAS key, or a namespace and one of its account keys to instantiate the client object. Please find the samples linked below for demonstration as to how to authenticate via either approach. Create client from connection string To obtain the required ...
(SAS) token, provide the token as a string. If your account URL includes the SAS token, omit the credential parameter. You can generate a SAS token from the Azure Portal under "Shared access signature" or use one of thegenerate_sas()functions to create a sas token for the storage ...
对于数据分析、交互式计算和数据可视化,Python 不可避免地会与其他广泛使用的开源和商业编程语言和工具进行比较,如 R、MATLAB、SAS、Stata 等。近年来,Python 改进的开源库(如 pandas 和 scikit-learn)使其成为数据分析任务的热门选择。结合 Python 在通用软件工程方面的整体实力,它是构建数据应用程序的主要语言的绝佳...
