Pretty straight forward but when you want to print multiple forms of the same type I don't see a way to easily clear the info, I have to overwrite or clear each field manually. Thank you, Fred McFaddin

It runs smoothly and quickly. It appears to have every feature I need in my daily work with PDF files, except one. It would be a fully completed utility if it included options for arranging/rearranging pages in PDF files. If it has that feature I am unable to find it. With this feature I'd rate it 5 stars.

If you simply want to concatenate a string 'n' times, you can do it easily using s = 'Hi' * 10. Another way to perform string append operation is by creating a list and appending strings to the list. Then use string join() function to merge them together to get the result string.
In Python, string is an immutable object. You can use '+' operator to append two strings to create a new string. There are various ways such as using join, format, string and appending the strings with space.
append() and extend() in Python If you append another list onto a list, the first list will be a single object at the end of the list. NOTE: A string is an iterable, so if you extend a list with a string, you'll append each character as you iterate over the string.
Use them based on your requirements. If you have to concatenate sequence of strings with a delimited, then use join() function. If some formatting is also required with concatenation, then use format() function or f-string. Note that f-string can be used with Python 3.6 or above versions.
To append() method in python adds a single item to the existing list. It doesn't return a new list of items but will modify the original list by adding the item to the end of the list. After executing the method append on the list the size of the list increases by one.
We have three methods to add new elements to a list: append(), insert(), and extend(). An empty list is created. To append() method adds an item at the end of the list. We append two strings. The insert() method places an element at a specific position indicated by the index number.
append(): append the object to the end of the list. Insert(): inserts the object before the given index. Extend(): extends the list by appending elements from the iterable.
If you simply want to concatenate a string 'n' times, you can do it easily using s = 'Hi' * 10. Another way to perform string append operation is by creating a list and appending strings to the list. Then use string join() function to merge them together to get the result string.
