Returning multiple values from pandas apply on a DataFrame

Question

I\'m using a Pandas DataFrame to do a row-wise t-test as per this example:

import numpy
import pandas

df = pandas.DataFrame(numpy.log2(numpy.ra         


        

Answer 1

Returning a Series, rather than tuple, should produce a new multi-column DataFrame. For example,

return pandas.Series({'pvalue': pvalue, 'mean_ratio': mean_ratio})
