how to make program runs again continue after else statement in python code example

Example 1: python how to skip iteration

nums = [7,3,-1,8,-9]
positive_nums = []

for num in nums:
    if num < 0: #skips to the next iteration
        continue
    positive_nums.append(num)
        
print(positive_nums) # 7,3,8

Example 2: python continue vs pass

Yes, there is a difference. 

continue forces the loop to start at the next iteration 
while pass means "there is no code to execute here" 
and will continue through the remainder or the loop body. 
continue will jump back to the top of the loop. 
pass will continue processing.
