如何从 Adwords API 中提取数据并放入 Pandas 数据框 [英] How To Pull Data From the Adwords API and put into a Pandas Dataframe

问题描述

我正在使用 Python 从 Google 的 Adwords API 中提取数据.我想将该数据放入 Pandas DataFrame 中，以便对数据进行分析.我正在使用 Google 提供的示例 在这里.

I'm using Python to pull data from Googles adwords API. I'd like to put that data into a Pandas DataFrame so I can perform analysis on the data. I'm using examples provided by Google here.

以下是我尝试将输出读取为熊猫数据框的尝试:

Below is my attempt to try to get the output to be read as a pandas dataframe:

from googleads import adwords
import pandas as pd
import numpy as np

# Initialize appropriate service.

adwords_client = adwords.AdWordsClient.LoadFromStorage()

report_downloader = adwords_client.GetReportDownloader(version='v201710')

# Create report query.
report_query = ('''
select Date, Clicks
from ACCOUNT_PERFORMANCE_REPORT
during LAST_7_DAYS''')

df = pd.read_csv(report_downloader.DownloadReportWithAwql(
    report_query, 
    'CSV',
    client_customer_id='xxx-xxx-xxxx', # denotes which adw account to pull from
    skip_report_header=True, 
    skip_column_header=False,
    skip_report_summary=True, 
    include_zero_impressions=True))

输出是类似于 csv 格式的数据和一个错误.

The output is the data in what looks like csv format and an error.

我知道我遗漏了一些基本的东西，而且我不完全了解如何将数据放入 Pandas 数据框.任何帮助将不胜感激.

I know I am missing something fundamental and I do not fully understand how to get data into a pandas dataframe. Any help would be greatly appreciated.

推荐答案

因此，如果有人好奇或遇到与我相同的问题，我可以找到我自己问题的答案.我必须import io 并将adwords 查询的输出写入我命名为output 的字符串.然后我使用 seek() 方法从头开始并使用 pandas read_csv 读取.

So I was able to find out the answer to my own question if anybody is curious or had the same problem I did. I had to import io and wrote the output from the adwords query to a string that I named output. I then used the seek() method to start from the beginning and read that using pandas read_csv.

from googleads import adwords
import pandas as pd
import numpy as np
import io

# Define output as a string
output = io.StringIO()

# Initialize appropriate service.
adwords_client = adwords.AdWordsClient.LoadFromStorage()

report_downloader = adwords_client.GetReportDownloader(version='v201710')

# Create report query.
report_query = ('''
select Date, HourOfDay, Clicks
from ACCOUNT_PERFORMANCE_REPORT
during LAST_7_DAYS''')

# Write query result to output file
report_downloader.DownloadReportWithAwql(
    report_query, 
    'CSV',
    output,
    client_customer_id='xxx-xxx-xxx', # denotes which adw account to pull from
    skip_report_header=True, 
    skip_column_header=False,
    skip_report_summary=True, 
    include_zero_impressions=False)


output.seek(0)

df = pd.read_csv(output)

df.head()
