The Joy of Computing using Python Programming Assignment
Question 1
You are given a list marks that has the marks scored by a class of students in a Mathematics test. Find the median marks and store it in a float variable named median. You can assume that marks is a list of float values.
Solution:
for i in range(0, len(marks)):
for j in range(i+1, len(marks)):
if marks[i] >= marks[j]:
marks[i], marks[j] = marks[j],marks[i]
#print(marks)
m=len(marks)//2
if len(marks)%2!=0:
median=marks[m]
else:
median=(marks[m-1]+marks[m])/2For answers or latest updates join our telegram channel: Click here to join

Question 3
You are given the dates of birth of two persons, not necessarily from the same family. Your task is to find the younger of the two. If both of them share the same date of birth, then the younger of the two is assumed to be that person whose name comes first in alphabetical order (names will follow Python’s capitalize case format).
The input will have four lines. The first two lines correspond to the first person, while the last two lines correspond to the second person. For each person, the first line corresponds to the name and the second line corresponds to the date of birth in DD-MM-YYYY format. Your output should be the name of the younger of the two.
Solution:
p1=input()
dob1=input()
p2=input()
dob2=input()
y1=int(dob1.split('-')[2])
y2=int(dob2.split('-')[2])
m1=int(dob1.split('-')[1])
m2=int(dob2.split('-')[1])
d1=int(dob1.split('-')[0])
d2=int(dob2.split('-')[0])
#print(y1,m1,d1)

Question 2
Write a program to take an input N and print Fibonacci sequence till N terms.
The Fibonacci sequence is a set of integers (the Fibonacci numbers) that starts with a zero, followed by a one, then by another one, and then by a series of steadily increasing numbers. The sequence follows the rule that each number is equal to the sum of the preceding two numbers.
Input
7
Output

8
Explanation: since the input is 7 there are seven terms. The first two terms are always 0 and 1. The third term is sum of first two terms. The fourth term is sum of second and third terms and so on.
Solution:
# Python program to display the Fibonacci sequence
n = int(input())
def recur_fibo(n):
if n <= 1:
return n
else:
return(recur_fibo(n-1) + recur_fibo(n-2))
# check if the number of terms is valid
if n <= 0:
print("Plese enter a positive integer")
