Lowering Error while trying to run parallel with prange

Hello. Whenever I run this code:

from numba import njit, prange

@njit(parallel=True)
def s(n):
    lis=[]
    for i in prange(n+1):
        lis.append(i)
    return lis

s(1)

It gives me LoweringError: And if I make lis into an empty np array:

from numba import njit, prange
import numpy as np

@njit(parallel=True)
def s(n):
    lis=np.empty(0)
    for i in prange(n+1):
        lis=np.append(lis,i)
    return lis

It gives ‘ValueError: Failed in nopython mode pipeline (step: convert to parfors) Use of reduction variable lis in an unsupported reduction function.’ And checking the internet I didnt find any solution to this. Thanks in advance

No problem RE: open/close.

As the above sample involving triplePartition is a more general question, I’d recommend asking it on the Numba discourse forum https://numba.discourse.group/ 😃 Thanks!
