That's a good point, unique could also be one of the attributes returned.

I'm not sure about missing, I think it might be unique instead.

Hah, leave it to the Azure experts to make a simple data display command so complicated. Next they'll be asking us to write Spark SQL queries in our sleep.

Hold up, are we sure about that? I thought display() only gave you the column names, data types, and maybe the first few rows. Where are you getting all these advanced stats from?

I'm pretty sure B and E are also part of the answer. You need to know the range and ordinal nature of the data to fully understand the DataFrame.

C, D, and missing are definitely the right attributes. The display() function in Synapse Analytics gives you the summary statistics including missing values and unique values.
