要写入具有左右边距和固定行长的文件的Python代码

def write_file_with_padding(file_path, content, line_length, left_padding, right_padding):
    formatted_content = "{:<{}}{}{:>{}}".format(left_padding, line_length, content, right_padding, line_length)
    
    with open(file_path, 'w') as file:
        file.write(formatted_content)

# 示例调用
file_path = "example.txt"
content = "Hello, world!"
line_length = 20
left_padding = ">>>"
right_padding = "<<<"

write_file_with_padding(file_path, content, line_length, left_padding, right_padding)
