Exercise

Uniform currencies

In this exercise and throughout this chapter, you will be working with a retail banking dataset stored in the banking DataFrame. The dataset contains data on the amount of money stored in accounts (acct_amount), their currency (acct_cur), amount invested (inv_amount), account opening date (account_opened), and last transaction date (last_transaction) that were consolidated from American and European branches.

You are tasked with understanding the average account size and how investments vary by the size of account, however in order to produce this analysis accurately, you first need to unify the currency amount into dollars. The pandas package has been imported as pd, and the banking DataFrame is in your environment.
