查找列表相同元素位置Python

Sure, I can help you find the position of the same elements in a list using Python. Here's an example code snippet:

my_list = [1, 2, 3, 2, 4, 1, 5, 6, 5]
duplicates = []

for i in range(len(my_list)):
    if my_list[i] in my_list[i+1:] and my_list[i] not in duplicates:
        duplicates.append(my_list[i])
        print("Duplicate element:", my_list[i])
        print("Position(s):", [j for j in range(len(my_list)) if my_list[j] == my_list[i]])

This will output:

Duplicate element: 1
Position(s): [0, 5]
Duplicate element: 2
Position(s): [1, 3]
Duplicate element: 5
Position(s): [6, 8]

Hope this helps!
