Swift --- Python --- Go --- Last statement Here,print('Last statement')is outside the body of the loop. Therefore, this statement is executed only once at the end. Example: Loop Through a String If we iterate through a string, we get individual characters of the string one by one...
Listsand other data sequence types can also be leveraged as iteration parameters inforloops. Rather than iterating through arange(), you can define a list and iterate through that list. We’ll assign a list to a variable, and then iterate through the list: sharks=['hammerhead','great white...
Aloopis a sequence of instructions that is continually repeated until a certain condition is reached. For instance, we have a collection of items and we create a loop to go through all elements of the collection. Loops in Python can be created withfororwhilestatements. Python for statement Py...
Python list loop shows how to iterate over lists in Python. Python loop definition Aloopis a sequence of instructions that is continually repeated until a certain condition is reached. For instance, we have a collection of items and we create a loop to go through all elements of the collecti...

Example 1: Print elements of the list with its index number using the enumerate() function In this program, the for loop iterates through the list and displays the elements along with its index number. numbers = [4, 2, 5, 7, 8] for i, v in enumerate(numbers): print('Numbers[',...

In this program, we have used a for loop to iterate through a sequence of numbers called numbers. In each iteration, the variable x stores the element from the sequence and the block of code is executed. Example 1: Count the Number of Even Numbers Let's use a for loop to count the ...
Python >>> def square(number): ... return number ** 2 ... >>> numbers = [1, 2, 3, 4, 5] >>> squared = map(square, numbers) >>> list(squared) [1, 4, 9, 16, 25] square() is a transformation function that maps a number to its square value. The call to map()...
