python - pandas : pandas. io.common.CParserError 错误:标记数据时出错

Question

当我运行这个脚本时，它不起作用，我不知道为什么。你能帮我吗？

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

错误:

Traceback (most recent call last):
  File "C:\Users\abc\Desktop\script.py", line 4, in <module>
    data1 = pd.read_csv(url)
  File "C:\Users\abc\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pandas\io\parsers.py", line 646, in parser_f

在 pandas 句柄中，您应该传入 csv 的位置。

示例: pd.read_csv(存档位置) 喜欢: pd.read_csv(myfile.csv)

仅此而已!
