Issue with columns of a Python visual

[Anonymous]

Hi,

It seems Python does not recognise the columns I select:

Anyone who knows why  this happens?

Some times it happens! dont worry

Use the name of the columns which are part of data model while using code

For example Total sales is coming as undefined , ignore undefined
