Jul 10, 2014 · You can use b as argument in inner loop. for b in range(56): for a in range(b+1, 57): print "a:", a, "b:", b you could try with smaller range to see all results on one screen. for b in range(6): for a in range(b+1, 7): print "a:", a, "b:", b result:

Mar 8, 2025 · Python programming language allows to use one loop inside another loop which is called nested loop. Following section shows few examples to illustrate the concept. The syntax for a nested while loop statement in the Python programming language is as follows:

Jul 25, 2014 · I am trying to combine a while loop with a for loop to iterate through some list but I am getting infinite loops. My code: l=[0,2,3,4] lo=0 for i in range(len(l)): while (True): lo+=1 if lo+l[i]>40: break print(lo) This code results in an endless loop.

Sep 2, 2021 · Nested while Loop in Python. In Python, The while loop statement repeatedly executes a code block while a particular condition is true. We use w a while loop when number iteration is not fixed. In this section, we will see how to use a while loop inside another while loop. The syntax to write a nested while loop statement in Python is as follows:

Mar 28, 2013 · Write a program that generates 100 random numbers (in the range of 1-1000) and keeps a count of how many of those random numbers are even and how many are odd. Display the results to the screen as seen in the sample output below. Hint: Use a while loop to loop 100 times. My result: random.randint(1,1000) num = num + 1. #print(num)

In this article, we will learn different types of loops in Python and discuss each of them in detail with examples. So let us begin. In programming, the loops are the constructs that repeatedly execute a piece of code based on the conditions.

Apr 1, 2025 · In Python, loops can be used to solve awesome and complex problems. You will likely encounter problems that would require you to repeat an action until a condition is met (while loop works best here) or a problem that requires you to perform an action on a bunch of items (for loop works best here).

Learn how to use loops within loops to solve complex problems, with practical use cases and techniques for effective implementation.

Sep 18, 2023 · In Python, there are two different types of loops: the for loop, and the while loop. Each loop has its own way of executing and exiting, and knowing when to use the correct loop is an important skill for beginner programmers.

Loops in Python automate repetitive tasks, improve efficiency, and simplify complex operations. This article explores different types of loops, how they work, and their real-world applications. We’ll also cover their benefits, best practices, and common mistakes to help you write better Python code. Contents:
