Pandas/Python如何存储循环值

Question

我正在尝试将多个代码循环到一个函数中，我可以成功地打印结果，但是我不能存储它们，只输出最后一个元素。循环似乎覆盖了先前生成的值，你能建议一下吗？

import yfinance as yf

y = ['SBUX', 'ICE']
b = {}

for x in y:
    ticker = yf.Ticker(x)
    d = ticker.get_info()
    for k, v in d.items():
        if k == 'zip' or k == 'sector' or k == 'symbol':
            b[k] = d[k]
    print(b)

代码的结果:

{'zip': '98134', 'sector': 'Consumer Cyclical', 'symbol': 'SBUX'}
{'zip': '30328', 'sector': 'Financial Services', 'symbol': 'ICE'}

如果代码外打印了b，则结果:

{'zip': '30328', 'sector': 'Financial Services', 'symbol': 'ICE'}

我想能够打印代码外的2行

Answer 1

您可以将它们追加到数据帧:

import yfinance as yf
import pandas as pd

new_df = pd.DataFrame()
y = ['SBUX', 'ICE']
b = {}

for x in y:
    ticker = yf.Ticker(x)
    d = ticker.get_info()
    for k, v in d.items():
        if k == 'zip' or k == 'sector' or k == 'symbol':
            b[k] = d[k]
    new_df = new_df.append(pd.DataFrame(b))
