给定 lists = [['hello'], ['world', 'foo', 'bar']]
如何将其转换为单个字符串列表？
combinedLists = ['hello', 'world', 'foo', 'bar']
最佳答案
lists = [['hello'], ['world', 'foo', 'bar']]
combined = [item for sublist in lists for item in sublist]
或者:
import itertools
lists = [['hello'], ['world', 'foo', 'bar']]
combined = list(itertools.chain.from_iterable(lists))
