使用python的Alpha Vantage API |如何遍历列表以生成多个图

pip install alpha_vantage

from alpha_vantage.timeseries import TimeSeries
import matplotlib.pyplot as plt

# 设置你的API密钥
api_key = 'YOUR_API_KEY'

# 创建一个TimeSeries对象
ts = TimeSeries(key=api_key)

# 定义要查询的股票代码列表
stock_symbols = ['AAPL', 'MSFT', 'GOOGL']

# 遍历股票代码列表并生成图表
for symbol in stock_symbols:
    # 获取股票数据
    data, meta_data = ts.get_daily(symbol, outputsize='full')
    
    # 提取日期和收盘价
    dates = list(data.keys())
    close_prices = [float(data[date]['4. close']) for date in dates]
    
    # 绘制图表
    plt.plot(dates, close_prices, label=symbol)

# 添加图例和标签
plt.legend()
plt.xlabel('日期')
plt.ylabel('收盘价')
plt.title('股票收盘价走势')

# 显示图表
plt.show()
