Pandas. Custom names for function values

Question

I have this code and it returns a dataframe with name and mean marks in ascending order.

p=mark_table.mean(axis=1)
p=p.sort_values()

Upon running, the name part has a column heading which already presented in the dataframe.but after i using the mean() there is no column name on the top of the mean values.Its just empty.
My question is that can i name the mean column as we do in SQL like below?👇

Select max(nums) as maximum

Thank you for your Time!

Answer 1

Could you show a snippet of the resulting data frame and describe where you want to add a name?

Answer 2

I want to print thee values in mean() with a custom column name.(currently blank)

Answer 4

Try p.columns = ['name', 'custom name']

Answer 5

I guess p.columns[1] = 'custom name' should also work
