Polars 使用 Arrow 在内存中管理数据,并依赖于 Rust 实现中的计算核心 来执行转换。类型转换通过cast()方法实现。 cast方法包括一个strict参数,该参数确定当 Polars 遇到无法从源DataType转换为目标DataType的值时的行为。默认情况下,strict=True,这意味着 Polars 将引发错误,通知用户转换失败,并提供无法转换的值的详...
总之,print(df)的实现涉及 Python 的高级功能、Pandas 库的排版机制以及底层操作系统的系统调用。¹³⁵ 源: 与必应的对话, 2024/4/7 (1) printf()等系统库函数是如何实现的? - 知乎. https://www.zhihu.com/question/28749911. (2) 如何漂亮打印Pandas DataFrames 和 Series - 知乎 - 知乎专栏. ht...
The code sample uses thepandas.read_csv()method to read the CSV files intoDataFrameobjects and theDataFrame.compare()method to compare the two DataFrames. TheDataFrame.compare()method returns aDataFramethat shows the differences stacked side by side. The resultingDataFramehas a MultiIndex withselfan...
