Question

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 cannot use a list comprehension (or any comprehension) - you will get to use one in the next version of the question. :)

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']

For example:

Test Result
tli3_list_1 = [4.1061, 2.54561, 4.16276, 2.33801, 6.71792, 5.54457, 6.49795, 2.1, 1.2, 1.4, 0.9, 3.8, 3.0] number = number_in_trophic_class(tli3_list_1, 'Microtrophic') print(f'{number} were Microtrophic.') 2 were Microtrophic.
tli3_list_1 = [4.1061, 2.54561, 4.16276, 2.33801, 6.71792, 5.54457, 6.49795, 2.1, 1.2, 1.4, 0.9, 3.8, 3.0] number = number_in_trophic_class(tli3_list_1, 'Mesotrophic') print(f"{number} were Mesotrophic.")

2 were Mesotrophic.

 

def trophic_class(trophic_level_index):
    '''Return the tropic classification indicated by the Trophic Level Index
    value provided'''
    if trophic_level_index >=6:
        return ('Hypertrophic')
    elif trophic_level_index >=5 and trophic_level_index < 6:
        return ('Supertrophic')
    elif trophic_level_index >=4 and trophic_level_index < 5:
        return ('Eutrophic')
    elif trophic_level_index >=3 and trophic_level_index < 4:
        return ('Mesotrophic')
    elif trophic_level_index >=2 and trophic_level_index < 3:
        return ('Oligotrophic')
    elif trophic_level_index >=1 and trophic_level_index < 2:
        return ('Microtrophic')
    elif trophic_level_index <1:
        return ('Ultra-microtrophic')
