'How to select every category of a column in a data frame?
I have a dataframe something like this.
I want to calculate the variance and standard deviation of co2_emission for each food_category by grouping and aggregating. And it has to be in this format
print(food_consumption.____(____)['co2_emission'].agg([____]))
This is I have done so far
print(food_consumption. .....(....)['co2_emission'].agg([np.var(food_consumption['co2_emission'], ddof=1),np.sqrt(np.var(food_consumption['co2_emission'], ddof=1))]))
I have to select the each category of the column named food_category. how to do that?
