Adding Numbers In List Script
-------------------------

Popcorn Hack #2

Pseudocode

nums ← 1 to 100 odd_sum ← 0

FOR EACH score IN nums IF score MOD 2 ≠ 0 THEN odd_sum ← odd_sum + score END IF END FOR

DISPLAY (“Sum of odd numbers in the list:”, odd_sum)

now in python

nums = range(1, 101) # This creates a range of numbers from 1 to 100 odd_sum = 0

for score in nums: if score % 2 != 0: odd_sum += score

print(“Sum of odd numbers in the list:”, odd_sum)

import random

# Define classes and teachers
classes = ['HPOE', 'AP CSP', 'AP Calc', 'AP Sem', 'APES']
teachers = ['Mr. Campillo', 'Mr. Mortenson', 'Ms. Nydam', 'Dr. Hall', 'Mr. Hendricks']

# Randomly select a class and a teacher
random_class = random.choice(classes)
random_teacher = random.choice(teachers)

# Print the random class-teacher combination
print(f"{random_class} with {random_teacher}")
