The name of the list (countdown, in the preceding example), or iterable that you want to loop over, followed by a colon (:). The code you want to run for each item in the iterable, separated by nested whitespace. Let's change that code to wait for one second between each number ...
languages = ['Swift','Python','Go']# access elements of the list one by oneforlanginlanguages:print(lang) Run Code Output Swift Python Go In the above example, we have created a list namedlanguages. As the list has 3 elements, the loop iterates3times. ...
“index_var “是”loop_control”的一个设置选项,”index_var”可以让我们指定变量,”loop_control”会将元素索引值存放在指定变量中 5.With_togeher [root@localhost cycle]# cat cycle.8.yml --- - name: cycle test8 hosts: test gather_facts: no vars: testlist1: [ A,B,C,D ] testlist2: [...

In this Python tutorial, you learned about aPython for loop with index, where you learned how to get the index value of an element or items in an iterable object such as a list. You learned about two functions, enumerate() and range(), which help you to get the index of the element...

1.List Comprehension / Generator 表达式 我们来看一个简单的例子。如果你想将一个数组转换为另一个数组: result = []for item in item_list:new_item = do_something_with(item)result.append(item) 如果你喜欢 MapReduce,你也可以使用 map,或者 Python 中的 List Comprehension: ...
// bare for loop with index:for(int i = 0; i < list.size(); i++) {System.out.println("item atindex "+ i+ " = "+ list.get(i));}// controlled loop with index:IntStream.range(0, list.size()).forEach(i ->System.out.println("item at index "+ i+ " = "+ list.get(...
