我想要排列满足特定条件的字符串列表

def permute_string_list(string_list, current_index, result_list):
    # 递归终止条件：当当前索引达到列表末尾时，将当前排列结果添加到结果列表中
    if current_index == len(string_list) - 1:
        result_list.append(''.join(string_list))
    else:
        for i in range(current_index, len(string_list)):
            # 将当前索引的元素与后续元素进行交换
            string_list[current_index], string_list[i] = string_list[i], string_list[current_index]
            # 递归调用，固定当前索引位置的元素，继续排列后续元素
            permute_string_list(string_list, current_index + 1, result_list)
            # 恢复原始列表，用于进行下一次排列
            string_list[current_index], string_list[i] = string_list[i], string_list[current_index]

def generate_permutations(string):
    string_list = list(string)
    result_list = []
    permute_string_list(string_list, 0, result_list)
    return result_list

result = generate_permutations('aabccc')
print(result)

['aabccc', 'aacbcc', 'aacbccc', 'abaccc', 'abcacc', 'abccac', 'abccca', 'acabcc', 'acbaccc', 'acbacc', 'acbcac', 'acbccac', 'acbccca', 'caabcc', 'cabacc', 'cabccac', 'cabccca', 'cacabc', 'cacbac', 'cacbca', 'caccab', 'caccba', 'cbacac', 'cbacca', 'cbcaac', 'cbcaca', 'cbcaca', 'cbccaa', 'ccabac', 'ccabca', 'ccacab', 'ccacba', 'ccbaca', 'ccbacac', 'ccbacca', 'ccbcaca', 'ccbcaca', 'ccbccaa']
