我想设置 pandas 数据框列的多个值 where 条件，但收到错误消息:
df[df['store_id'] == 'UK00023', ['sale','startdate','enddate']] = [100, str(datetime.now()), str(datetime.now())]
But I got this error:
raise ValueError('Length of values does not match length of '
ValueError: Length of values does not match length of index
最佳答案
试试这个:
df.ix[df['store_id'] == 'UK00023', ['sale','startdate','enddate']] = [100, str(datetime.now()), str(datetime.now())]
