谈到pandas数据的行更新、表合并等操作,一般用到的方法有concat、join、merge。但这三种方法对于很多新手来说,都不太好分清使用的场合与用途。 构造函数 方法描述DataFrame([data, index, columns, dtype, copy])构造数据框 属性和数据 方法描述Axesindex: row labels;columns: column labelsDataFrame.as_matrix([...

Two representations of the data are available. The default representation uses a strict schema per parser and converts known numbers to int/float JSON values. Certain known values of None are converted to JSON null, known boolean values are converted, and, in some cases, additional semantic ...
- merge 函数(比 SQL 的 JOIN 还灵活) 但要注意!别在 Jupyter 里直接显示大 DataFrame(会卡死内核),用 df.head(10) 或 df.sample(5) 预览才是正道。 三、Rich:让命令行秒变高端黑 (这个必须吹爆!)以前总觉得终端输出灰蒙蒙的很 low,直到发现这个库——字体颜色、进度条、表格排版全支持!
