EXERCISE - 8 FUNCTIONS

A) Write a function ball_collide that takes two balls as parameters 

and computes if they are colliding. Your function should return a Boolean 

representing whether or not the balls are colliding.
B) Find mean, median, mode for the given set of numbers in a list.

A) AIM: Write a function ball_collide that takes two balls as parameters and 

computes if they are colliding. Your function should return a Boolean 

representing whether or not the balls are colliding.

SOURCE CODE:

import math
def ball_collide(ball_tuple1,ball_tuple2):
    d=math.sqrt((ball_tuple1[0]-ball_tuple2[0])**2 + 

(ball_tuple1[1]-ball_tuple2[1])**2)
    if(d<=(ball_tuple1[2]+ball_tuple2[2])):
        return True
    else:
        return False

ball_tuple1=(-2,-2,3)
ball_tuple2=(1,1,3)
collision=ball_collide(ball_tuple1,ball_tuple2)
if(collision):
    print("Balls are collide.")
else:
    print("Balls are not collide.")

OUTPUT:

Balls are collide.



B) AIM: Find mean, median, mode for the given set of numbers in a list.

SOURCE CODE:

def mean(numlist):
    no_of_eles=len(numlist)
    summ=sum(numlist)
    avg=summ/no_of_eles
    print("Mean for given set of numbers is : ",avg)
    return

def median(numlist):
    numlist.sort()
    if(len(numlist)%2!=0):
        i=len(numlist)//2
        print("Median for given set of numbers is : ",numlist[i])
    else:
        i=len(numlist)//2
        print("Median for given set of numbers is : ",

(numlist[i-1]+numlist[i])/2)
    return

def mode(numlist):
    modedict={}
    mincount=1
    for ele in numlist:
        maxcount=numlist.count(ele)
        if(maxcount>=mincount):
            mincount=maxcount
            modedict[ele]=mincount
    if(mincount==1):
        print("Mode for given set of numbers is : None")
    else:
        print("Mode for given set of numbers is : ",end='')
        for ele in modedict:
            if(modedict[ele]==maxcount):
                print(ele,end=' ')
    return

numlist=[]
n=int(input("Enter number of elements to be insert:"))
for i in range(n):
    ele=int(input("Enter element:"))
    numlist.append(ele)
mean(numlist)
median(numlist)
mode(numlist)

OUTPUT:

Enter number of elements to be insert:4
Enter element:9
Enter element:5
Enter element:7
Enter element:3
Mean for given set of numbers is :  6.0
Median for given set of numbers is :  6.0
Mode for given set of numbers is : None
