I usually used list_wo_no_duplicate = list(set(list_with_ducplicates))  to remove duplicates.  Although I think there is no harm for not setting the variable to list again as set in most cases.

For example:

def formatList(seq):
    seen = set()
    seen_add = seen.add
    return [ x for x in seq if not (x in seen or seen_add(x))]

There are loads of topics about this on stackoverflow and Google. This example is taken from http://stackoverflow.com/questions/480214/how-do-you-remove-duplicates-from-a-list-in-python-whilst-preserving-order and also keeps the order of your list!

 

A second option could be to create a second list, which only contains the clean values. In case you would like to keep both lists.

for i in mylist:
     if i not in newlist:
          newlist.append(i)

list = set(list) is this correct?

It can be easily done by given python code:

duplicate_list = [1, 3, 5, 1, 4, 5]

new_list = list(set ( duplicate_list))

Hi, I can get the id of duplicate records and use set() function which works perfectly for item ids but I would like to add the quantities of duplicate values. Can you guide how to sum the quantities of all ids in one2many?
