(hint use display command for formatting the query output in a table format)

Use Python to work on the firecalls dataframe and answer the following questions:

1) Write a Python query to retrieve the address of the first 20 lines of the data.

2) Write a Python query to retrieve the number of fire calls by each neighborhood district, order them descending.

3) Write a Python query to retrieve the number of fire calls from this address '1485 Bayshore Bl. Hint the filter command takes input as string filter(column == value)
