• Do not add statements that call print, input , or open , or add an import statement. • Do not use any break or continue statements. We are imposing this restriction (and we have not even taught you these statements) because they are very easy to abuse, resulting in terrible, hard to read code. • Do not modify or add to the import statements provided in the starter code. import math from typing import List, TextIO # For simplicity, we'll use "Station" in our type contracts to indicate that # we mean a list containing station data. # You can read "Station" in a type contract as: List[int, str, float, float, int, int, int] 23 # where the values at each index represent the station data as described in the # handout on Quercus. # A set of constants, each representing a list index for station information.

TODO 2 Complete the TODO by finding the locations of the data samples for each iris flower type. Hint: Use the code for how we found all the setosa_locs as an example! Using iris_df, find the location of all the data sample locations for the versicolor class which has a label of 1. To do so, use NumPy's np.where() function. Using iris_df, find the location of all the data sample locations for the virginica class which has a label of 2. To do so, use NumPy's np.where() function. setosa_locs = np.where(iris_df['class'] == 0)[0] # TODO 2.1versicolor_locs = # TODO 2.2virginica_locs = todo_check([ (type(versicolor_locs) is np.ndarray, "'versicolor_locs' is not type np.ndarray.
