If you wrap range() inside reversed(), then you can print the integers in reverse order. So the program is using the for loop and the range() function to iterate over a sequence of numbers and for each iteration, it prompts the user to enter two numbers and print the sum of those numbers. But Python does have a built-in reversed function. Execute the statement (s) inside the For loop block. If an item is available, go inside the loop, else go to step 3. The basic structure is this: for item in sequence: execute expression where: for starts a for loop. When program execution enters For loop for the first time, it checks if there is an item from iterable. Python prides itself on readability, so its for loop is cleaner, simpler, and more compact. The values entered by the user are stored in variables a and b, and then the program print the sum of a and b as output. The for loop in Python looks quite different compared to other programming languages.The for loop iterates five times, each time prompting the user to input a number using the built-in input() function. The second for loop uses the range() function to create an iterator that generates a sequence of numbers from 0 to 4.The for loop iterates over the numbers in the sequence and prints each one to the screen. The first for loop uses the range() function to create an iterator that generates a sequence of numbers from 0 (inclusive) to 21 (exclusive) with a step of 2.This program is a Python script that demonstrates the use of the for loop and the built-in range() function. The range function generates a sequence of numbers, starting from 0 by default, and increments by 1 (also by default), and stops before a specified number.

This is very useful, since the numbers can be used to index into. You can use the range function in a for loop in Python to repeat a block of code a specific number of times. The for loop is a control flow statement that is used to repeatedly execute a group of statements as long as the condition is satisfied. The python range() function creates a collection of numbers on the fly, like 0, 1, 2, 3, 4. The for loop is used to repeat a specific block of code which you want to repeat a fixed number of times.
