Load entire tables
In the last exercise, you saw that data.db has two tables. weather has historical weather data for New York City. hpd311calls is a subset of call records made to the city's 311 help line about housing issues.
In this exercise, you'll use the read_sql() function in pandas to load both tables. read_sql() accepts a string of either a SQL query to run, or a table to load. It also needs a way to connect to the database, like the engine in the provided code.
