Python: How to extend or append multiple elements in list comprehension format?

Question

I\'d like to get a nice neat list comprehension for this code or something similar!

extra_indices = []
for i in range(len(indices)):
    index = indices[i]
          


        

Answer 1

You can use two loops in list comp -

extra_indices = [index+i for index in indices for i in range(3)]
