如何删除ASCII编号13？

import os

def remove_ascii_13(file_path):
    with open(file_path, 'r') as file:
        content = file.read()
    
    content = content.replace('\r', '')  # 将回车符替换为空字符串
    
    with open(file_path, 'w') as file:
        file.write(content)

# 遍历指定目录下的所有文件
def traverse_directory(directory):
    for root, dirs, files in os.walk(directory):
        for file in files:
            file_path = os.path.join(root, file)
            remove_ascii_13(file_path)

# 示例调用
traverse_directory('/path/to/directory')  # 替换指定目录下所有文件中的回车符
