相关疑难解决方法(0)

我想检查一个列表中的任何项目是否存在于另一个列表中.我可以使用下面的代码简单地完成它,但我怀疑可能有一个库函数来执行此操作.如果没有,是否有更多的pythonic方法来实现相同的结果.

In [78]: a = [1, 2, 3, 4, 5]

In [79]: b = [8, 7, 6]

In [80]: c = [8, 7, 6, 5]

In [81]: def lists_overlap(a, b):
   ....:     for i in a:
   ....:         if i in b:
   ....:             return True
   ....:     return False
   ....: 

In [82]: lists_overlap(a, b)
Out[82]: False

In [83]: lists_overlap(a, c)
Out[83]: True

In [84]: def lists_overlap2(a, b):
   ....:     return len(set(a).intersection(set(b))) > 0
   ....:
