向列表中的重复值追加一个数字- python

def append_number_to_duplicates(lst):
    seen = {}
    result = []
    for item in lst:
        if item not in seen:
            seen[item] = 1
            result.append(item)
        else:
            seen[item] += 1
            result.append(f"{item}-{seen[item]}")
    return result

# 示例
original_list = ['apple', 'banana', 'apple', 'orange', 'banana', 'banana']
new_list = append_number_to_duplicates(original_list)
print(new_list)

['apple', 'banana', 'apple-2', 'orange', 'banana-2', 'banana-3']
