python - 去掉 Pandas 中的多个名字

Question

我正在尝试将多名称列转换为 python 中的单名称列。现在，列名称如下所示:

   [('passengers', 'January'),
   ('passengers', 'February'),
   ('passengers', 'March'),
   ('passengers', 'April'),
   ('passengers', 'December'),
   'Total']

但我正在尝试得到这个:

  ['January',
   'February',
   'March',
   'April',
   'December',
   'Total']

有什么建议吗？

Answer 1

不是 Pandas :-):

l=[('passengers', 'January'),
   ('passengers', 'February'),
   ('passengers', 'March'),
   ('passengers', 'April'),
   ('passengers', 'December'),
   'Total'] # Or pandas then get data to list.
print([i[-1] if isinstance(i,tuple) else i for i in l])

输出:

['January', 'February', 'March', 'April', 'December', 'Total']
