为什么我一直得到相同的输出？

Question

I am creating a for loop and I keep getting the output twice:

    totalelements = len(uniquevalueslist)
    for id in [23, 45, 76]:
        if id not in uniquevaluelist:
            stmt = f"""INSERT INTO..."""
            for x in range(totalelements):
                stmt = stmt + f" SELECT...."
                if x < totalelements-1:
                    stmt = stmt + "UNION ALL " 
                else:
                    stmt += stmt   

my output is that I get the INSERT INTO Statement Twice

Answer 1

the if statement is inside the for loop. this means it will be evaluated each time you loop through the items.
