What is list iteration for loop in Salesforce?
The list or set iteration for loop iterates over all the elements in a list or set. When executing this type of for loop, the Apex runtime engine assigns variable to each element in list_or_set, and runs the code_block for each value.
How does a for loop work in a list?
A for loop iterates through items the same way as while and do-while loops, but it can also iterate through a list or set. (You can use for loops with SOQL too, but that’s for another day.)

How do you loop back to the beginning of a list Python?
We can loop back to the start by using a control flow statement, i.e., a while statement. To do that, wrap the complete program in a while loop that is always True. What is this? Moreover, add a continue statement at a point where you want to start the program from the beginning.
How do you loop through a list in darts?
In the following Dart Program, we take a list containing some elements. Then we use Dart For loop with index to traverse through all elements of the list. During each iteration, we just print the element, demonstrating that we can access the element. Thus we can loop through list items using for loop.
What is a for loop?

What is loop in Apex?
As you learned in Apex Basics for Admins, a loop is a block of code that is repeated until a specified condition is met. Loops allow you to do a task over and over again. Apex has three types of loops. You’ve used the while and do-while loops already. The third type is the for loop.
How does a loop work?
Here's how it works: When the loop starts, it initializes a counter. Then it checks whether the loop condition is true. If the answer is yes, then the loop performs an action, updates the counter, and returns to check the condition again. When the answer to the condition check is no, the loop stops.
Why do you use a while loop?
If you want the loop to stop based on a condition other than the number of times it runs you should use the while loop. For loops are more concise because they keep the three parts—the variable, the condition, and the increment—together in one statement.
