Merging every 2 elements of a list in Python

So let’s say I have a list as follows:

Li = ['1', '2', '3', '4', '5', '6', '7', '8']

I want to have a list modification to have this:

Li = ['12', '34', '56', '78']

Is it possible to merge every 2 elements of a list together?

Answer

>>> Li = ['1', '2', '3', '4', '5', '6', '7', '8']
>>> [''.join(Li[i:i+2]) for i in range(0, len(Li), 2)]
['12', '34', '56', '78']
