Q1:

Bonnie is writing a Python program for her math class so she can check her answers quickly. She is having some difficulties, however, because when she enters values like 3.5 or 2.71 her program throws an error. She has heard of your expertise in Python and asks for your help. What error is being thrown and how can she fix the program to accept values like 3.5 or 2.71?

from math import sgrt def distance (coorl, coor2): 'Accepts two tuples that represents points on a graph and calculates the distance between them.''. coor1 (len (coor1) (len (coor2) 2), "First parameter not a point on a 2D graph. assert == 2) , "Second parameter not a point on a 2D graph. coor2 assert #Unpacks the elements from coor1 and assigns them #to x1 and y1 respectively (3ame for the next line) х1, у1 coor1 x2, y2 coor2 = 2 x distance (x1 x2) 2 y distance (y1 y2) _ distance = sqrt (x distance y distance) return distance ").split ) first coordinates input "Enter the first coordinates separated by a space: input ("Enter the second coordinates separated by a space: ").split ) second coordinates = [int (i for i in first coordinates [int (i for i in second coordinates first coordinates second coordinates = print (distance (first coordinates, second coordinates))

Error :

ValueError: invalid literal for int() with base 10: '3.5'

Fix :

first_cordinates = [float(i) for i in first_cordinates]

second_cordinates = [float(i) for i in second_cordinates]
