what point is it appropriate to build an index by hand

Define the function  number_in_trophic_class(tli3_values, classification) which takes a list of trophic level index values and a trophic classification, returning the number of lakes in that trophic class. For this version of the question you MUST use a list comprehension. You cannot use a for loop or while loop in your answer. Notes: You must include, and use/call your trophic_class function in your submission. Your tropic_class function must work in the same way it did for Question 2. You can assume that classification will always be valid, i.e. it will always be one of the states in the following list: ['Hypertrophic', 'Supertrophic', 'Eutrophic', 'Mesotrophic', 'Oligotrophic', 'Microtrophic', 'Ultra-microtrophic'] There are several ways to proceed, but you will probably find either the len function or the count method of the list class useful in conjunction with your list comprehension. For example: Test Result tli3_list_1 = [4.1061, 2.54561, 4.16276, 2.33801,…

Focus on dictionary methods, use of functions, and good programming styleFor this assignment, you will create a glossary (dictionary) of technical terms and definitions. It will be set up as a Python dictionary structure. The file glossary_starter.py is a complete starter framework for the assignment. It includes some initial values for the dictionary. It is long because most of the code has already been written for you.Your task is to complete the five individual functions for adding and deleting terms, looking up terms, listing them, and printing out both the terms and definitions. These functions are all short, just a couple of lines, and use basic dictionary methods and techniques.  Here is some sample output. Glossary system 1) Add a term 2) List terms 3) Get a definition  4) Delete a term 5) Print out dictionary 6) Quit  Enter your choice: 2 argument dictionary hashmap list set 5 terms  Glossary system  1)  Add a term 2) List terms 3) Get a definition  4) Delete a term 5) Print…

What precisely does it mean when you use the delete operator?

In python don't import libraries

Why is it very important to know how the GROUPING SETS phrase works?

given dictionaries, d1 and d2, create a new dictionary with the following property. For each entry(a,b) in d1, if a is not a key of d2 then add (a,b) to the new dictionary. For each entry (a,b) in d2, if a is not a key of d1 then add (a,b) to the new dictionary. For example, if d1 is {2:3, 8:19, 6:4, 5:12} and d2 is {2:5, 4:3, 3:9}, then the new dictionary should be {8:19, 6,4, 5:12, 4:3, 3:9}. using puthon

Complete the Swap() method in main.c to exchange the values of the num field of two Number struct objects, num1 and num2.
