删除Python列表中没有数字的单词的方法是什么？

Question

 a = ['in 1978 by', 'History', 'members', 'albums', 'June 4th, 1979', 'October 7,1986): "The Lounge', 'In 1984 the', 'early 1990s; prominent']

上面的列表有一些单词，比如历史，成员中没有数字，所以我想删除它们

 # output would be
 a = ['in 1978 by', 'June 4th, 1979', 'October 7, 1986', 'In 1984 the', 'early 1990s; prominent']

Answer 1

下面是一个较短的替代方法，使用any()和string.digits：

from string import digits

a = ['in 1978 by', 'History', 'members', 'albums', 'June 4th, 1979', 
     'October 7,1986): "The Lounge', 'In 1984 the', 'early 1990s; prominent']

[x for x in a if any(y in x for y in digits)]

=> ['in 1978 by', 'June 4th, 1979', 'October 7,1986): "The Lounge',
    'In 1984 the', 'early 1990s; prominent']
