What is the optimal method in Python for concatenating items in a distinct list in a particular sequence?

edit

One optimal method in Python for concatenating items in a distinct list in a particular sequence is by using the join() method.

Example:

lst = ['hello', 'world', 'how', 'are', 'you']

sequence = [2, 1, 0, 4, 3]

result = ''.join([lst[i] for i in sequence])

print(result)

Output:

howworldhelloyouare

Explanation:

In this example, we have a list lst and a sequence sequence. The sequence indicates the order in which we want the items from the list to be concatenated.

We use a list comprehension to create a new list with the items from the original list in the desired sequence.

Then, we use the join() method to concatenate the items in the new list into a single string. The separator used between the items is an empty string (''), which means that there will be no separator between the concatenated items.
