Love your solution here is another one if you want to build the string straight up leave comments on what you think
class Solution:
def customSortString(self, order: str, s: str) -> str:
h_map = collections.Counter(s)

ans = ""
for i in order:
if i in h_map:
ans += i * h_map[i]
h_map.pop(i)

for i in h_map:
ans += i * h_map[i]

return ans
