Hence, here we are going to use groupby() method first, then we will apply the agg() method on this groupby object and finally we will join the columns of groupby object with their respective values by mapping them into a list.Let us understand with the help of an example,Python cod...
For example, if we only have categorical variables and try to apply mean function, we will get an error: We can diversify the examples but the underlying logic is the same. Groupby function can be used as the first step in exploratory data analysis process because it gives us an idea ...
