Filtering/selecting 变量输出 = 简单的简单问题，但我不知道如何搜索正确的解决方案

Question

我确定这很简单，但我找不到合适的词来解释我对 Google 的意思，所以我的搜索结果是空的。

我有一个正在打印到控制台的变量。都好。

我想要 filter/select 变量输出，这样我就可以在新变量中引用它。我只是不知道该命令的正确语法。

这是变量：

all_orderbooks = client.get_orderbook_ticker()

print(all_orderbooks)

然后输出大量数据，这里是一个片段：

我希望能够 filter/select 文本中的特定主题，即 "symbol:" 然后只显示符号。

我想我必须创建一个新变量并指定我想要的目标，即 print(all_orderbooks.symbol) 或 print(all_orderbooks)_symbol，但迄今为止的努力没有结果。

如有任何帮助，我们将不胜感激。

这是我的决定

all_orderbooks = client.get_orderbook_ticker()
for order in all_orderbooks:
    ordersymbol = (order['symbol'])
    print(ordersymbol)

非常感谢

Answer 1

好的，我想出来了，它有效，但如果有更好的方法，我肯定很乐意学习:)

all_orderbooks = client.get_orderbook_ticker() all_orderbooks 的订单： ordersymbol = (order['symbol']) 打印（订单符号）

谢谢大家！
