Question

我正在使用CSV文件中的销售数据集。当我尝试使用pandas read_csv方法加载该数据集时，出现错误UnicodeDecodeError: 'ascii' codec can't decode byte 0xae in position 16: ordinal not in range(128)，我不知道如何解决此问题。我进行了搜索，得到了this link，但仍然无法解决我的问题。我尝试了以下

import pandas as pd

sales=pd.read_csv("Superstore-Sales.csv")
sales.head(5)

这里是完整错误

Answer 1

看看sales=pd.read_csv("Superstore-Sales.csv", encoding='latin1')是否有用。

Answer 2

您可以尝试以下方法：

address = (r"C:\--------------------/Superstore-Sales.csv")
sales = pd.read_csv(address, encoding='latin1') 
sales.head()
