我不确定是不是你要的：
from time import time
old = [str(i) for i in range(10**7)] # set up a list
insert = ['n'] # set up an insert list
def test(old, insert):
t0 = time()
add = (old[i : i + 1024] + insert for i in range(0, len(old), 1024))
new = []
for i in range(0, len(old), 1024):
new += next(add)
print(time() - t0)
return new
new = test(old, insert)
输出结果：
0.2487800121307373
