如何从python中带有文本和数字的不同元组列表中获取所有字符串

Question

我在从下面的元组列表中获取文本列表时遇到了很大的挑战，这是我从 nltk 库中获取的关键字

[('supreme court justice ruth bader ginsburg may', 14.0),
 ('justice ruth bader ginsburg rightly holds', 12.0),
 ('vintage ruth— ‘ straight ahead', 10.0),
 ('fellow supreme court colleagues penned', 10.0),
 ('could make things better', 8.0),
 ('neighbor sanford greenberg says', 8.0),
 ('live. ” ginsburg ’', 8.0),]

这是我想得到的预期输出

['supreme court justice ruth bader ginsburg may',
 'justice ruth bader ginsburg rightly holds',
 'vintage ruth— ‘ straight ahead',
 'fellow supreme court colleagues penned',
 'could make things better',
 'neighbor sanford greenberg says', 
 'live. ” ginsburg ’']

谢谢
