Multiple column in a single boxplot using seaborn-CodePudding

In relation with this

But I encountered an issue while using this code.

cn = ['AgeUnder18', 'Age19to25', 'Age26to29']
sns.boxplot(x=cn, y='AveMonthSpend', data=df)

Error:

The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
