How Do I Show Every Other Element in a Python List?Firstly, let’s create a list of strings… Show
Cool, the slice operator returns every other element starting from the first. The slice operator follows the syntax below (this is actually called extended slice syntax). string[start:end:step]When start and end are not specified the entire list is taken into account. The step value allows to skip some of the items in the list, in our example we have passed 2 as the value of the step. That’s why the output prints every other string in the list. If we want to start from the second element in the list the syntax becomes the following: >>> print(countries[1::2]) ['United Kingdom', 'United States']This time we have started by index 1, remember that the index for lists starts from zero. “print every second element of list python” Code Answer’severy second value python python by Tremendous Enceladus 0 Try out the enumerate function for yourself in this quick exercise. Complete the skip_elements function to return every other element from the list, this time using the enumerate function to check if an element is on an even position or an odd position. typescript by Comfortable Cod 0 Add a Grepper Answer Python answers related to “print every second element of list python”

Print Reverse Range in Python using for-loopHow to print numbers in reverse Order in Python using for-loop? Method 1: Using step If you set the step value to -1, for-loop print the value in reverse order. for i in range(10, 1, -1): print(i) Output: Method 2: Using reversed() reversed() is the built-in method that returns the sequence in reverse order. for i in reversed(range(2, 11)): print(i) Output: 10 9 8 7 6 5 4 3 2If you need to print the element in the reverse method, I would recommend using the first method. Using reversed() method adds extra computation. So in terms of performance, avoid using reversed() method. Just another example. Print every second element in decreasing order from the given range in Python. for i in range(10, 1, -2): print(i) Output: This is all about this tutorial to reverse range in Python. Any doubts?
