For loops, in general, are used for sequential traversal. As a result, firstly the outer for Loop with range(1, 3) gets called and then the inner for Loop having range(4, 7) gets called iteratively. The most basic for loop is a simple numeric range statement with start and end values. By using our site, you This provides us with the index of each item in our colors list, which is the same way that C-style for loops work. for i in range(4): print(i) Output (1) 0 1 2 3 All the integers within this range will be added. In this tutorial, we will learn how to loop in steps, through a collection like list, tuple, etc. This provides us with the index of each item in our colors list, which is the same way that C-style for loops work. Python 3 - for Loop Statements - The for statement in Python has the ability to iterate over the items of any sequence, such as a list or a string. The code under the else clause executes after the completion of the “for” loop. Write Python code that prints numbers from 10 - 0 (inclusive). How to get the Iteration index in for loop in Python.

Example 2: for i in range(x, y, step) In this example, we will take a range from x until y, including x but not including y, insteps of step value, and iterate for each of the element in this range using for loop. Inside the loop, you can put the code to execute each time when the iteration perform. range() function allows to increment the “loop index” in required amount of steps.
