python - 如何使用 pandas 将 1 列添加到多个数据框？

Question

    import pandas as pandaimport
    
#tickers = ['nflx','goog','fb','amzn','aapl']
    
    nflx = pandaimport.read_csv('nflx.csv')
    goog = pandaimport.read_csv('goog.csv')
    fb   = pandaimport.read_csv('fb.csv')
    amzn = pandaimport.read_csv('amzn.csv')
    aapl = pandaimport.read_csv('aapl.csv')
    
    nflx['ticker'] = 'nflx'
    goog['ticker'] = 'goog'
    fb['ticker'] = 'fb'
    amzn['ticker'] = 'amzn'
    aapl['ticker'] = 'aapl'


#for index in tickers:
#    index = pandaimport.read_csv('' + index + '.csv')
    
#for index in tickers:
#    @index['Address'] = address

如何将 1 列添加到数据帧的字符串数组中？我觉得这一切都应该用for循环来完成......
