你需要:

c = [1,2,3,4,4,4,6,7,6]

dup_c = []
for idx,i in enumerate(c):
    if i in dup_c:
        c[idx] = "*"
    else:
        dup_c.append(i)

print(c)

输出:

[1, 2, 3, 4, '*', '*', 6, 7, '*']

使用 np.where

import numpy as np

id_ = [2,4,5,6,8]  # as id is a keyword in Python

df['Final'] = np.where(df['id'].isin(id_), 0, df['Final'])
