To get the mean of multiple columns together, first, create a dataframe with the columns you want to calculate the mean for and then apply the pandas dataframe mean function. For example, let's get the mean of the columns "petal_length" and "petal_width" # mean of more than one columns print(df[ ['petal_length', 'petal_width']].mean()) Output:.
