1. Loss of Decimal Precision Metadata A column stored as Decimal(18,0) in Delta Lake is converted to an object dtype in pandas. This conversion strips away the original precision (18,0), leading to issues when writing back. 2. Schema Re-Inference in write_deltalake() ...
Python >>> pd.set_option("display.max.columns", None) While it’s practical to see all the columns, you probably won’t need six decimal places! Change it to two:Python >>> pd.set_option("display.precision", 2) To verify that you’ve changed the options successfully, you can ...
decimalstr,默认为'.'用作小数点的字符。例如,欧洲数据可以使用,。float_precisionstring,默认为 None指定C 引擎应使用���个转换器来处理浮点值。选项为None表示普通转换器,high表示高精度转换器,round_trip表示往返转换器。lineterminatorstr(长度为 1),默认为None用于将文件分成行的字符。仅与 C 解析器...
