How can i add multiple column names in pandas DataFrame?

Question

I have a data set of 256 columns and i want to add column names such as : ['N1', 'N2' ... 'N256']. Is there a quick way to do it ?

I have tried something like that :

df.columns = ['S' for x in range(1,257)]

But this code just adds the S in every column. How can i add the indexes also ?

Answer 1

Is this:

df.columns = ['N'+str(x) for x in range(1,257)]
