Count positive and negative numbers Program Code

# Count positive and negative numbers in set
numbers = {15, -3, 28, -7, 0, -12, 45, -9, 33, -21, 10}
print("Set:", numbers)

pos_count = 0
neg_count = 0
zero_count = 0
pos_list = []
neg_list = []

for num in numbers:
    if num > 0:
        pos_count += 1
        pos_list.append(num)
    elif num < 0:
        neg_count += 1
        neg_list.append(num)
    else:
        zero_count += 1

print(f"Positive: {pos_count} → {pos_list}")
print(f"Negative: {neg_count} → {neg_list}")
print(f"Zeros: {zero_count}")
