print("Combind list without duplicates:",combinedList) Output: Combind list without duplicates: [40, 10, 50, 20, 60, 30] That’s all about how to combine two lists in python Was this post helpful? Let us know if this post was helpful. Feedbacks are monitored on daily basis. Please...
after concatenating the lists using a + operator, the resultant list is passed to the in-built set() method. As Python sets do not have any duplicate elements, this removes all the duplicates from the concatenated list. As we require a list, this set is...

Merging two balanced lists is much more efficient than merging lists of disproportionate size. Picking a min_run value that’s a power of two ensures better performance when merging all the different runs that the algorithm creates. Combining both conditions above offers several options for min_run...
The + operator can combine two lists to create a new list value in the same way it combines two strings into a new string value. The * operator can also be used with a list and an integer value to replicate the list. Enter the following into the interactive shell: >>> [1, 2, 3...

Solution: Use the following three steps to combine two lists and remove the duplicates in the second list: Convert the first and second lists to a set using the set(...) constructor. Use the set minus operation to get all elements that are in the second list but not in the first list...

Combining multiple lists into one Comprehensions allow for multiple iterators and hence, can be used to combine multiple lists into one. a = [1, 2, 3] b = [7, 8, 9] [(x + y) for (x,y) in zip(a,b)] # parallel iterators #...
