仅查找行中的重复项

from collections import Counter

def find_duplicates(row):
    # 将行分割成单词列表
    words = row.split()

    # 计算每个单词出现的次数
    counts = Counter(words)

    # 找到出现次数大于1的单词
    duplicates = [word for word, count in counts.items() if count > 1]

    return duplicates

# 示例用法
row = "apple banana apple orange banana"
duplicates = find_duplicates(row)
print("重复项：", duplicates)
