Use python to write a code

Problem 1: Environmental Monitoring

You are given a nested list in which the sublists contain tuples!

Example:

samples = [ [('frog','H'), ('toad','D') ], [('trout','H'), ('salmon','S'), ('catfish','H')] ]

Here each species is either healthy H, dead D or sick S. Access the health status of a specified animal using multi-indexing.

Count how many are healthy using two nested for loops. List will be bigger and different on each version.
