通过 Pandas 在 Jupyter Notebook 中读取 CSV 时出错

Question

我是 python 和 pandas 的新手，我正在尝试使用常规代码.i.e 在 jupyter notebook 中导入结构化的 csv 文件

import pandas as pd
df=pd.read_csv("Datasets/Border_Crossing_Entry_Data")
df.head(5)

但每次我收到以下错误时，请帮助我，因为我应该提交我的作业

<ipython-input-11-33127abc1814> in <module>
      1 import pandas as pd
----> 2 df=pd.read_csv("Datasets/Border_Crossing_Entry_Data")
      3 df.head(5)

我认为您只需要在文件名中添加.csv。所以，请尝试：

import pandas as pd
df=pd.read_csv("Datasets/Border_Crossing_Entry_Data.csv")
df.head(5)
