將字典轉換為 pandas 數據框

Question

我正在運行一個腳本來使用 google pytrend 庫分析基於關鍵字的相關關鍵字搜索。 但是我得到的 output，我想將它轉換為 pandas 數據框，我嘗試了幾種方法，但沒有用。 csv 導出后文件為空。

import pandas as pd                        
from pytrends.request import TrendReq
pytrend = TrendReq()
pytrend.build_payload(kw_list=['AUDI','corona'], cat=0, timeframe='2021-03-01 2022-03-14',geo="TH")
related_queries = pytrend.related_queries()
related_queries.values()

#Covert to pandas dataframe
file1 = pd.DataFrame.from_dict(related_queries)
file1.to_csv('file2.csv' , index = True)

#Related query output
dict_values([{'top':             query  value
0       audi ราคา    100
1         audi tt     55
2         audi a5     51
3              a5     50

24        audi a8      8, 'rising':                   query  value
0          audi wong ig  10000`}])`

Answer 1

可能的解決方案如下：

import pandas as pd                        
from pytrends.request import TrendReq

pytrend = TrendReq()

pytrend.build_payload(kw_list=['AUDI','corona'], cat=0, timeframe='2021-03-01 2022-03-14', geo="TH")

#get related queries
related_queries = pytrend.related_queries()
related_queries.values()

alldata = []

for i in range(len(list(related_queries.values()))):
    #build lists dataframes
    top = list(related_queries.values())[i]['top']
    rising = list(related_queries.values())[i]['rising']

    #convert lists to dataframes
    dftop = pd.DataFrame(top)
    dfrising = pd.DataFrame(rising)
    
    alldata.append(dftop)
    alldata.append(dfrising)

#join two data frames
allqueries = pd.concat(alldata, axis=0)

allqueries.reset_index(drop=True, inplace=True)

allqueries.to_csv('file.csv', index = True)

allqueries dataframe 的示例如下所示：
