将文件装入Jupyter Notebook

Question

我已经尝试过我被指示的方式，并将csv中的代码移动到我的Jupyter Notebook所在的文件夹中。它仍然没有读取它。我还试图将其转换为数据框架，并让它"描述"。我将在下面发布代码和错误。请帮助!提前感谢!

import pandas as pd
fish = pd.read_csv('c:\Users\Manaconda3\Scripts\Fish')
fish2 = pd.DataFrame(fish)
fish2.to_csv('fishdata.csv')
fish2.describe()

Answer 1

您可以尝试重命名您的文件，将.csv附加到您的文件名

Answer 2

您需要指定要读取的文件的扩展名。例如:对于csv文件，您的代码看起来像

fish = pd.read_csv('c:\Users\Manaconda3\Scripts\Fish.csv')

或者如果你的文件和你的代码在同一个目录下，你可以使用完整的文件名

fish = pd.read_csv('Fish.csv')

Answer 3

您已经清楚地知道read_csv的参数是无效的。

OSError: [Errno 22] Invalid argument: 'c:\Users\Mx07naconda3\Scripts\Fish'

您似乎错过了cvs文件，例如table.csv。

您可以尝试使用os.getcwd()检查当前工作目录是否与csv文件相同
