Q3. From the previous question, for what values of n is the number 7 appended to list a. 7 6 8 9
Answer: 8 , 9
Q4. What does the following code perform ?
It converts any input list into a new list which is filled with some alternative even and odd numbers. It converts any input list into a new list such that at even indices, the value is a multiple of an even number and at odd indices, the value is either odd or even number. It converts any input list into a new list such that at even indices, the value is multiple of 2 and at odd indices, the value is multiple of 3. It converts any input list into a new list, which follows no pattern.
Answer: It converts any input list into a new list such that at even indices, the value is a multiple of an even number and at odd indices, the value is either odd or even number.

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])/2

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.
if (y1>y2): print(p1,end=””) elif (y2>y1): print(p2,end=””) else: if(m1>m2): print(p1,end=””) elif(m2>m1): print(p2,end=””) else: if(d1>d2): print(p1,end=””) elif(d2>d1): print(p2,end=””) else: print(min(p1,p2),end=””) For answers or latest updates join our telegram channel: Click here to join
