Question

1. Write a function that inputs a list of numbers and a percentile value from 0 to 1 and have the function return the element that is at that percentile (or greater than). You can use this website for the steps https://www.indeed.com/career-advice/career-development/how-to-calculate-percentile check out the step for “Follow these steps to calculate the kth percentile”

def percentileReturn(list1,percentile):#function which returns the list of elements which are greater than or equal to the percentile
list2=[i for i in list1 if i>=percentile] #creating list2 which have elements from list1 which are greater than or equal to percentile
return list2 #returning list2
values=list(map(float,input("Enter numbers: ").split())) #values
percentile=float(input("Enter percentile: ")) #percentile
print(percentileReturn(values,percentile)) #calling percentileReturn function and testing for a sample value

This is what I put and my prof said: I get an error.     values=list(map(float,input("Enter numbers: ").split())) #values

ValueError: could not convert string to float: '1,2,3,4'

this is for python

Answer 1

Thanks for the question, Since your professor is giving input the grades separated by comma and not space, you need to split() it by comma.

Here is the updated code and output screenshot. Please check with your professor and let me know for any changes.

==========================================================================

import math

# function which returns the list of elements which are greater than or equal to the percentile
def percentileReturn(list1,  percentile):
    size = len(list1)
    return sorted(list1)[int(math.ceil((size * percentile))) - 1]


values = list(map(float, input("Enter numbers: ").split(',')))  # values
percentile = float(input("Enter percentile: "))  # percentile
print(percentileReturn(values, percentile))  # calling percentileReturn function and testing for a sample value
