get_comments_product_feat(start_date, end_date)函数中,comment_date_end是不是有误呢？

[zhangluustb]

get_comments_product_feat(start_date, end_date)：
if:pass
else:
comments = pd.read_csv(comment_path)
comment_date_end = end_date
comment_date_begin = comment_date[0]
for date in reversed(comment_date):
if date < comment_date_end:
# comment_date_begin = date
comment_date_end = date
break
