写入CSV文件Python3问题

Question

我正在使用poloniex交易者API获取实时市场报价信息。它在控制台上完美运行。当我要求市场报价回报我得到这{'last': '0.07269671', 'high24hr': '0.07379970', 'quoteVolume': '71582.56540639', 'isFrozen': '0', 'lowestAsk': '0.07277290', 'percentChange': '-0.00551274', 'id': 148, 'low24hr': '0.07124645', 'highestBid': '0.07269671', 'baseVolume': '5172.41552885'}

问题是它只存储项目名称/列表名称，如 - low24hr, lowestAsk, highestBid etc。没有自己的价值一样 - low24hr : 0.07124645

polo = Poloniex() 
ticker_data = (polo('returnTicker')['BTC_ETH']) 

out = csv.writer(open("myfile.csv","w"), delimiter=',',quoting=csv.QUOTE_ALL,) 
out.writerow(ticker_data) 
print(ticker_data) 

这里是我的CSV文件看起来喜欢 -

Answer 1

你的问题是，out.writerow(ticker_data)只接收字典的关键字并将它们写入文件。尝试使用csv.DictWriter：

with open('myfile.csv', 'w', newline='') as csv_file: 
    # Pass the keys of the `ticker_data` as the fieldnames. 
    writer = csv.DictWriter(csv_file, fieldnames=ticker_data, quoting=csv.QUOTE_ALL) 
    # Write the fieldnames. 
    writer.writeheader() 
    # Write the values. 
    writer.writerow(ticker_data) 

Answer 2

with open('my_file.csv', 'w') as f: 
    for key, value in ticker_data.items(): f.write('{0},{1}\n'.format(key, value))
