1. 使用itertools生成排列和组合: re>from itertools import permutations, combinations items = [1, 2, 3] perms = list(permutations(items, 2)) combs = list(combinations(items, 2)) print(perms, combs) 2. 使用zip(*iterables)解压多个列表: list1 = [1, 2, 3] list2 = ['a', 'b', 'c...
result = any(numbers)# True result = all(numbers)# False。0使结果为False 7. 迭代模块 itertools 模块提供了一组函数来处理迭代器。该模块中的函数包括 chain 、 product 和 permutations 。 import itertools numbers = [1, 2, 3] result = list(itertools.permutations(numbers)) # 输出所有排列组合 # ...
