Using Exception to avoid yahoofinance error

问题

代码中的问题在于使用了错误的异常类。要获得期望的输出，你需要捕获 yf.utils.exceptions.HTTPError 异常，而正确的异常类应该是 yfinance.exceptions.HTTPError。以下是修正后的代码和期望的输出：

  1. import yfinance as yf
  3. stcks = ['AXSM', 'FB', 'AAPL']
  4. for i in stcks:
  5.     try: 
  6.         sec = yf.Ticker(i).info['sector']
  7.     except yf.exceptions.HTTPError as err:
  8.         print('error')
  9.         continue
  10.     else: 
  11.         print('hi')

修正后的代码应该输出：

  1. hi
  2. error
  3. hi

这样，当无法获取列表中某个项目的数据时，代码将继续迭代处理下一个项目。

英文:

I'm simply trying to use an exception to handle HTTPErrors for items like 'FB' to continue iterating through the list but I can't seem to get around the issue. Code:

  1. stcks = ['AXSM', 'FB', 'AAPL']
  2.    for i in stcks:
  3.         try: 
  4.             sec = yf.Ticker(i).info['sector']
  5.         except yf.utils.exceptions.HTTPError as err:
  6.             print('error')
  7.             continue
  8.         else: 
  9.             print('hi')

Output

  1. hi
  2. HTTPError: 404 Client Error: Not Found for url: https://query2.finance.yahoo.com/v10/finance/quoteSummary/FB?modules=summaryProfile%2CfinancialData%2CquoteType%2CdefaultKeyStatistics%2CassetProfile%2CsummaryDetail&ssl=true

During handling of the above exception, another exception occurred:

  1. AttributeError
  2. Traceback (most recent call last)
  3.     Cell In[243], line 5
  4.       3 try    : 
  5.       4     sec = yf.Ticker(i).info['sector']
  6.     ----> 5 except yf.utils.exceptions.HTTPError as err:
  7.       6     print('error')
  8.       7     continue
  10. AttributeError: module 'yfinance.utils' has no attribute 'exceptions'

How can I get the desired output provided that I cannot get data for one of the items in the list?:

  1. hi
  2. hi

使用requests异常来捕获缺失的股票代码(HTTPError)：

  1. import requests
  3. stcks = ['AXSM', 'FB', 'AAPL']
  4. for i in stcks:
  5.     try: 
  6.         sec = yf.Ticker(i).info['sector']
  7.     except requests.HTTPError as err:
  8.         print('error')
  9.         continue
  10.     else: 
  11.         print('hi')

输出：

  1. hi
  2. error
  3. hi
英文:

Use requests exception to catch missing tickers (HTTPError):

  1. import requests
  3. stcks = ['AXSM', 'FB', 'AAPL']
  4. for i in stcks:
  5.     try: 
  6.         sec = yf.Ticker(i).info['sector']
  7.     except requests.HTTPError as err:
  8.         print('error')
  9.         continue
  10.     else: 
  11.         print('hi')

Output:

  1. hi
  2. error
  3. hi
