return "Ms. "+ name
else:
return "Invalid gender specified."

# Example usage
name = input("Enter the name: ")
gender = input("Enter the gender (M/F): ")

updatedName = addPrefix(name, gender)

3. Write a program that has a user defined function to accept the coefficients of a quadratic equation in variables and calculates its
determinant. For example: if the coefficients are stored in the variables a,b,c then calculate determinant as b2-4ac. Write the appropriate
condition to check determinants on positive, zero and negative and output appropriate result.
Ans.
def calculateDeterminant(a, b, c):

determinant = b**2 - 4*a*c
return determinant

print("Enter the coefficients for quadratic equation")
a = float(input("a: "))
b = float(input("b: "))
c = float(input("c: "))

# Calculate determinant
determinant = calculateDeterminant(a, b, c)

if determinant > 0:
print("Positive Determinant")
print("The quadratic equation has two distinct real roots.")
elif determinant == 0:
print("Zero determinant")
print("The quadratic equation has one real root (a repeated root).")
else:
print("Negative Determinant")
print("The quadratic equation has two complex conjugate roots.")
4. ABC School has allotted unique token IDs from (1 to 600) to all the parents for facilitating a lucky draw on the day of their Annual day
function. The winner would receive a special prize. Write a program using Python that helps to automate the task. (Hint: use random
module)
Ans.

import random
# Number of participants with unique token IDs (1 to 600)
numParents = 600

def luckyDraw(numParents):
winId = random.randint(1, numParents)
return winId

# Perform the lucky draw
winner = luckyDraw(numParents)
print("Winner of the lucky draw!", winner)
