如何查找在文件中多次出现的重复字符串

def find_duplicate_strings(file_path):
    # 打开文件并读取内容
    with open(file_path, 'r') as file:
        content = file.read()

    # 初始化字典用于存储字符串出现次数
    string_counts = {}

    # 遍历文件内容字符串，计算每个字符串出现次数
    for word in content.split():
        # 如果字典中已存在该字符串，增加出现次数
        if word in string_counts:
            string_counts[word] += 1
        # 如果字典中不存在该字符串，添加到字典并置次数为1
        else:
            string_counts[word] = 1

    # 输出重复的字符串
    duplicate_strings = [string for string, count in string_counts.items() if count > 1]
    if len(duplicate_strings) == 0:
        print("文件中没有重复字符串")
    else:
        print("文件中重复的字符串：")
        for string in duplicate_strings:
            print(string)

# 调用函数并传入文件路径
find_duplicate_strings("path/to/file.txt")
