读取 CSV 文件时出现 UnicodeDecodeError
UnicodeDecodeError reading a CSV file
我使用以下代码读取 CSV 文件:
address=r'C:\Users\ssadangi\Desktop\Lynda Python data analytics\Ch02_05\Superstore-Sales.csv'
df=pd.read_csv(address,index_col='Order Date',parse_dates=True)
代码给我这个错误:
UnicodeDecodeError Traceback (most recent call last)

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xae in position 16: invalid start byte
在处理上述异常的过程中,又发生了一个异常:
