    Assuming you have a nested loop,
    
    ```
    for letter in letters:
     for number in numbers:
      for symbol in symbols:
       print(letter + number + symbol)
    ```
    
    If the code fails halfway through, you print out ERROR-letter-number-symbol. Then you use the following function to calculate the Nth position in the product list:
    
    [Link to the stackoverflow](https://stackoverflow.com/questions/72882207/whats-the-mathematical-formula-for-a-nested-loop)
    
    ```
    def position(list_of_lists, tup):
        t = 1
        res = 0
        for lst, x in zip(reversed(list_of_lists), reversed(tup)):
            res += t * lst.index(x)
            t *= len(lst)
        return res
    ```
    
    From this point we can resume the loop!
