So, can write a for loop inside another for loop and this is called nesting. Python For Loop is just like another Python command or statement. In the following example, we shall write an else block with for loop. This else block is executed after the for loop is completed with all the elements in the iterable. Just like in an if-else statement, you can use an else block with for loop. The print statement after the continue statement in the for loop has been skipped and continued with the next element in the loop, which is 8. When x is 7, continue statement is executed. In the following example program, we shall continue the for loop, when the value of element is 7. When continue statement is executed, the for loop continues with the execution of next element in the iterable, rather than completing all the statements in the for loop body. We can skip the execution of further statements in the for loop body, during that iteration, using continue statement. If there had not been the break statement, for loop would have executed until x is 10. To realize this, we will use a if statement and execute break statement when the condition evaluates to True. In the following program, we shall break the for loop, when the value of element is 7. But, we can break the for loop and end it before it has actually run for all the elements in the iterable using break statement.

Python Program mystring = 'pythonexamples'įrom the syntax and flow diagram, we know that for loop will be over only after executing statement(s) for all the elements in the iterable. In this example, we will take a string and iterate over the characters using for loop. As long as we can get an iterable for the object, we can use for loop. Python Program mydictionary = Īs set is an unordered collection, the order in which for loop accesses the next item from the set is not obvious. In this example, we will take a dictionary and iterate over the key:value pairs of the dictionary using for loop. Programs Example 4: For Loop with Dictionary We could access this item of tuple in for loop using variable x. Python Program mytuple = ('python', 'programming', 'examples', 'programs') In this example, we will take a tuple and iterate over the items of tuple. In this case, we are able to access the item using variable x. Please note that, during each iteration, we are able to access the item for which the loop is running. In this example, we will take a list and iterate over the items of list using for loop. But, you may write as many statements as required by following indentation. The statements inside the for loop are executed for each of these elements.įor these examples, the body of for loop has only one print statement. So, the range has items: 25, 26, 27 and 28. In this example, we will use a for loop to iterate over a range of numbers. At that time, as there is no next item, the for loop is deemed completed, and the execution continues with the next statements in the program. After executing the statement(s) for all items in iterable, the execution comes to a situation where there is no next item in the iterable. The for loop block executes for each item in the iterable. If True, then the statement(s) are executed again for this next item. After execution of the statement(s), the program checks if there is next item available. If an item is available, the program executes statement(s) inside for block.

When program execution enters for loop for the first time, it checks if there is an item from iterable.
