Can we use ELSE statement without IF in Python?
In most programming languages (C/C++, Java, etc.), the use of the else statement has been restricted with conditional if statements. But Python also allows us to use the else condition with for loops. The else block just after for/while is executed only when the loop is NOT terminated with a break statement.

Can the FOR loop have an optional else statement?
Both for and while loops in Python also take an optional else suite (such as the if statement and the try do statement), which is executed if the loop iteration completes normally. In other words, the else suite will be executed if we don’t exit the loop in a way other than its natural way.
How do you skip the rest of a for loop?
The continue statement skips the rest of the statements in a for or while loop and begins the next iteration. To break out of the loop entirely, use a break statement. continue is not defined outside of a for or while loop. To exit a function, use return .
When to use else with for loop in Python?
The else statement is executed after the execution of the for loop. However, if you use the break statement within the for loop. The else statement will not be executed and it also exits the loop. If you use an else statement after the loop and put some code to execute.
When to use a break statement in Python?
Break statement In Python, the break statement gives you the opportunity to break out of a loop when an outer condition is triggered. You will place the break statement within the code block below your loop statement, usually after a conditional statement. Let’s look at an example that uses the break statement in a for loop:
When to use the else block in Python?
But Python also allows us to use the else condition with for loops. The else block just after for/while is executed only when the loop is NOT terminated with a break statement. This type of else is useful only if there is an if condition present within the loop that somehow depends on the loop variable.
When to break out of a loop in Python?
I myself came to know of them much later. The common construct is to run a loop and fetch an item. If the element is found, we exit the loop using the break statement. There are two scenarios in which the cycle can end. The first is when the element is found and a break is found.
