FileNotFoundError: File b'newdata.txt' does not exist: b'newdata.txt' 我只是个新手，以上程序来自网站，说是可以运行，我运行后出现了错误提示信息，请求高手更改，，谢谢！ 此行读取文件
df = pd.read_table('newdata.txt', header=None, sep=',')
但程序中并未创建文件。 如何创建？请冬雪雪冬给与指导，万分感谢 如何创建？请冬雪雪冬给与指导，万分感谢 如何创建？请冬雪雪冬给与指导，万分感谢 如何创建？请冬雪雪冬给与指导，万分感谢 如何创建？请冬雪雪冬给与指导，万分感谢 本帖最后由 gywjj 于 2019-12-18 14:36 编辑
这个文件是你电脑上的，最好你跟一个绝对路径，别人的位置和你的不一定一样
你在什么网上下的，上面应该有这个文件，如果你找不到，你可以自己创建一个
格式应该是这个样子的
