熊猫read_html打破

Question

我正在尝试进行抓取，当1个Ticker值没有任何信息时，过程中断。我希望它继续显示在列表中。

我尝试了不同的方法来完成这项工作。我检查了一下，雅虎网站上没有可供读取的表格。

import pandas as pd

# The 3rd Ticker value ABMD will break this code
ticker = ["MMM", "NUVR", "ABMD" "ABT"]

for tic in ticker:
    inc_state = pd.read_html('https://finance.yahoo.com/quote/' + tic + '/financials?p' + tic, na_values=['No Acquirer'])
    df = inc_state[0][2][0]
    df3 = pd.DataFrame(inc_state)
    # This if statement doesnt work ugh!
    if df != 'No Acquirer':
        print("-" * 20)
        print(tic)
        print(df)
    else:
        continue

我得到的是前两个项目都能正常工作，然后又崩溃了。
