[Solved] How to make a new list from list of values of occurrences and value? [closed]

by


You can use zip with a nested list comprehension:

values = [10.5,20.2, 50.0]
occ = [3,5,1]

result = [x for x, y in zip(values, occ) for _ in range(y)]

Alternatively, without using range:

result = [elem for x, y in zip(values, occ) for elem in [x] * y]

Output:

[10.5, 10.5, 10.5, 20.2, 20.2, 20.2, 20.2, 20.2, 50.0]
