listtools.overwrite_slices_at

abjad.tools.listtools.overwrite_slices_at(l, pairs)

Overwrite slices in l according to pairs.

  • pairs must be a list (anchor_index, length) pairs. The function then copies the value of l[anchor_index] over l[anchor_index + 1], l[anchor_index + 2], ..., l[anchor_index + length - 1].

Return new list.

abjad> l = range(10)
listtools.overwrite_slices_at(l, [(0, 3), (5, 3)])
[0, 0, 0, 3, 4, 5, 5, 5, 8, 9]
abjad> l = range(10)
listtools.overwrite_slices_at(l, [(0, 99)])
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
