Pivot on multiple columns

[memo]

I want to pass multiple column as argument to pivot a dataframe  in pyspark pivot like

mydf.groupBy("id").pivot("day","city").agg(F.sum("price").alias("price"),F.sum("units").alias("units")).show().

One way I found is to create multiple df with different pivot and join them which will result in multiple scan. But is there any other way to do this?

Like how will the pass multiple values to the pivot function? It only takes one argument. I tried with sending an array, list. But it is throwing errors
