Description

pretty much all Python calculation engines support show method , see pyspark documentation https://spark.apache.org/docs/latest/api/python/reference/pyspark.sql/api/pyspark.sql.DataFrame.show.html

it is just for convenience especially when used with SQL

stinodego commented 4 months ago

We want to support this. Implementation will look like:

show method on DataFrame and LazyFrame
It will print to the console and not return anything
The method will have some parameters to directly configure some Config printing parameters
In notebooks we want to use the _html_repr, otherwise we want to use the regular repr

HI, is this being already worked on? I can be assigned if needed, I am new to the codebase and want to start contributing, will need some time and guidance to implement.

mnurpeiissov commented 4 months ago

I will proceed with implementation as @stinodego outlined, is that ok?

guilhem-dvr commented 2 weeks ago

Hi, I'm not seeing any work from @mnurpeiissov so I'm guessing he didn't proceed with the implementation.

I'm willing to implement this feature, would that be okay? I've already drafted an implementation and tests.
