In this article, we discuss the list length of a Pandas dataframe. First, create a dataframe and then use the map() function with len parameters. This displays the dataframe with length column.
In another way, you can get the lastNelements from a list using list slicing. For example, you first get the length of the list using the len() function. you then subtract N from the length of the list to get the starting index for our slice. You use this starting index to slice ...
