2.Elements are treated as unique based on their position, not on their value. So if the input elements are unique, there will be no repeat values in each combination. 1. 2. 3. 4. AI检测代码解析 # A Python program to print all combinations # of given length with duplicates in input ...
# %% def permutation1(arr, k, combination=False): ''' arr : 传入数组 k : 选出的元素个数 combination : True代表是组合,默认是排列,有顺序。 ''' def permutation_sub(temp, arr, result, s): ''' 递归方法 temp : 以参数形式存储单个结果 arr : 原始数组 result : 存储所有排列结果 s : 组...
Python Copy 使用itertools.combinations()可得到输入集合中元素的所有的组合。比如: >>>fromitertoolsimportcombinations>>>forcincombinations(items,3):...print(c)...('a','b','c')>>>forcincombinations(items,2):...print(c)...('a','b')('a','c')('b','c')>>>forcincombinations(items,...
