Question

当我运行此脚本时，它不起作用，我不知道为什么。你能救我吗？

import pandas as pd
data1 = pd.read_csv(url)
print(data1)

错误：

    data1 = pd.read_csv(url)

谢谢！

Answer 1

在pandas句柄中，你应该传递csv的位置。

实施例： pd.read_csv（location.of.archive）喜欢： pd.read_csv（myfile.csv）

这就是全部！

Answer 2

就像那样无法分辨。我建议下载PyCharm，并在调试模式下运行代码，一步一步查看可能存在的问题。

请参阅JetBrains文档。
