Turn flat list into two-tuples
python
Solution
This is quite short:
zip(input, input[1:])[::2]
Problem
Is there a single line expression to accomplish the following: ``` input = ['this', 'is', 'a', 'list'] output = [('this', 'is'), ('a', 'list')] ``` My initial idea was to create two lists and then zip them up. That would take three lines. The list will have an even number of elements.
