计数并显示一行在文件中重复的次数

def count_duplicate_lines(filename):
    lines = {}  # 用字典存储每一行及其重复次数

    with open(filename, 'r') as file:
        for line in file:
            line = line.strip()  # 去除行尾的换行符和空格

            if line in lines:
                lines[line] += 1
            else:
                lines[line] = 1

    for line, count in lines.items():
        print(f"行 '{line}' 重复了 {count} 次")

# 调用函数并传入文件名
