I need to expand the following code in order to incorporate 3 lists.

```
for a, b in zip(product_old, product_name):
    print('{:<6} {}'.format(a, b))

```

However when I expand to:

```
for a, b, c in zip(product_old, product_name, product_new):
    print('{:<6} {}'.format(a, b, c))

```

The returned print does not include the new list. How can I fix this? I have tried DataFrame, however this isn't suitable due to the fact there doesn't seem to be an option to left justify the data.

Thank you!
