#create a tuple tuplex = "w", "j" ,"c", "e" print(tuplex) #tuples are immutable, so you can not remove elements #using merge of tuples with the + operator you can remove an item and it will create a new tuple tuplex
#create a tuple tuplex = tuple("index tuple") print(tuplex) #get index of the first item whose value is passed as parameter index = tuplex.index("p") print(index) #define the index from which you want to search index = tuplex.index() p
Java中循环遍历元素,一般有for循环遍历,foreach循环遍历,iterator遍历. 先定义一个List对象 List<String> list = new ArrayList<>(); list.add("1"); list.add("2"); list.add("3"); 一.普通for循环遍历 for (int i = 0; i < list.size(); i++) { System.out.prin
python循环删除列表元素 觉得有用的话,欢迎一起讨论相互学习~Follow Me 常见错误 常见错误一:使用固定长度循环删除列表元素 # 使用固定长度循环pop方法删除列表元素 num_list_1 = [1, 2, 2, 2, 3] for i in range(len(num_list_1)): if num_list_1[i] == 2: num_list_1.pop(i) else: print(num_list_1[i]) print("num_list_1:", num
