datacompy 1.0.0b4

Dataframe comparisons in Python

DataComPy

DataComPy is a package to compare two DataFrames (or tables) such as Pandas, Spark, Polars, and even Snowflake. Originally it was created to be something of a replacement for SAS's PROC COMPARE for Pandas DataFrames with some more functionality than just Pandas.DataFrame.equals(Pandas.DataFrame) (in that it prints out some stats, and lets you tweak how accurate matches have to be). Supported types include:

• Pandas
• Polars
• Spark
• Snowflake

[!IMPORTANT] datacompy is progressing towards a v1 release. During this transition, a support/0.19.x branch will be maintained solely for v0.19.x users. This branch will only receive dependency updates and critical bug fixes; no new features will be added. All new feature development should target the v1 branches (develop and eventually main).
