"Using Python, code to find the smallest and largest planet mass
(if known), and plot these as two curves against the year of
discovery"
Basically looking to use data from an excel sheet where
'disc_year' and 'pl_mass' are columns of data; and code Python to
find the maximum value of mass and the minimum value of mass for
each year, then plot this as two curves. There are multiple planets
for any given year hence multiple values for mass. Below...
