Question

我想在Google趋势历史数据中找到自相关。非官方API使用Pandas Dataframes，我决定使用它的内置自相关函数，这里是代码：

from pytrends.request import TrendReq

z = ["animales"]

google_username = "xxx@gmail.com"
google_password = "xxxxxxxxx"
path = ""

pytrend = TrendReq(google_username, google_password, custom_useragent='')

pytrend.build_payload(kw_list=z, timeframe='today 5-y', geo='MX')

interest_over_time_df = pytrend.interest_over_time()

print(interest_over_time_df[z].autocorr(lag=1))

之前已经有用，我不知道我改变了什么，我的代码抛出了以下错误：

Traceback (most recent call last):
  File "C:/Users/Rafael/PycharmProjects/untitled/test.py", line 19, in <module>
     print(interest_over_time_df[z].autocorr(lag=1))
  File "C:\Users\Rafael\AppData\Local\Programs\Python\Python35-32\lib\site-packages\pandas\core\generic.py", line 2744, in __getattr__
    return object.__getattribute__(self, name)
AttributeError: 'DataFrame' object has no attribute 'autocorr'

Answer 1

some_dataframe["col_name"]返回Series。 some_dataframe[["col_name"]]会返回DataFrame。 autocorr is a Series function

熊猫自相关函数错误：＆＃39; DataFrame＆＃39;对象没有属性＆＃39; autocorr＆＃39;
