使用python批量转换编码时多余换行的问题

最近使用python批量将项目中的GBK编码文件转换为UTF8时遇到了会自动给每一行结尾多添加一个换行符的问题这样会导致多行宏命令失效
原因是使用文本读写模式 ‘w’ ‘r’
修改为使用 ‘wb’ ‘rb’ 使用二进制接收在使用utf8编码为str然后以二进制方式写入就可以了
完整脚本如下

    (filepath, filename) = os.path.split(file)
    (shortname, extension) = os.path.splitext(filename)

    with open(filename, 'rb') as f:
        data = f.read()
