'''
Step 1: Initialize sum = 0
Step 2: Begin iterating over each element in the list.
Step 3: First iteration (ele = 2)
Check if ele is int → True
Check if ele is odd (2 % 2 != 0) → False
sum remains 0

Step 4: Second iteration (ele = 3)
Check if ele is int → True
Check if ele is odd (3 % 2 != 0) → True
Add ele to sum: sum = 0 + 3 = 3

Step 5: Third iteration (ele = 5)
Check if ele is int → True
Check if ele is odd (5 % 2 != 0) → True
Add ele to sum: sum = 3 + 5 = 8

Step 6: Fourth iteration (ele = 4)
Check if ele is int → True
Check if ele is odd (4 % 2 != 0) → False
sum remains 8

Step 7: Fifth iteration (ele = 6)
Check if ele is int → True
Check if ele is odd (6 % 2 != 0) → False
sum remains 8

Step 8: Loop ends after all elements processed
Step 9: Print sum → 8
