Python for Loop (With Examples)
For example, # iterate from i = 0 to 3 for _ in range(0, 4): print('Hi') ... Here, the loop runs four times. In each iteration, we have displayed Hi. Since we are not using the items of the sequence (0, 1, 2, 3) in the loop body, it is better to use _ as the loop variable.

You're following a recipe for potato soup. It says "wash and peel five potatoes." But you only know how to wash and peel one potato. So you wash and peel one potato, then another, then another, until you've done it to five potatoes. That's a for loop: "for each of five potatoes, wash the potato, then peel it." More on reddit.com

June 29, 2021New to python and I need some help with loops.
Loops allow you to repeat a block of code over and over again. There are two main types of loops in Python - for loops and while loops. For loops are used when you know how many times you want to repeat the code. # This will print the numbers 0 to 4 for i in range(5): print(i) The range(5) part creates numbers from 0 to 4. The for loop will go through each of those numbers, storing them in the variable i, and print them out. While loops are used when you don't know exactly how many times you need to repeat the code. You keep looping as long as some condition is true. # This will print numbers as long as x is less than 5 x = 0 while x < 5: print(x) x = x + 1 This starts x at 0, then keeps looping as long as x is less than 5. Each time, it prints x and then adds 1 to x. Once x reaches 5, the loop stops. More on reddit.com

August 31, 2023For Loops - Best Ways to learn.
What's the difficulty exactly? The basic idea is you've got a bucket of items, and you want to take each one one at a time and do something with it, until you've gone through all the items. Think of it like "for each item in bucket", where the "each" is silent/invisible. Example: bucket = [1, 2, 3] for item in bucket: print(item) Sometimes you don't care about the actual items in the bucket; you just want to use them as a counter to make the loop run X number of times. Then it's common to use range() as a convenient way to make a bucket of a given size. for item in range(3): print('Huzzah!') The bucket can be anything that's an "iterable". So, lists, tuples, strings, dictionaries, generators, etc. If an item drawn from the bucket has multiple parts, you can use "tuple unpacking" to reference them individually. bucket = ['a', 'b', 'c'] for index, value in enumerate(bucket): print(index, value) More on reddit.com

June 22, 2023Understanding the For Loop
range() generates numbers. If you only pass 1 argument range(5) it will start from 0 and keep going up, and stop before hitting 5. I know sounds strange but that's how it works. So range(5) gives you 0 1 2 3 4 If you pass 2 arguments, range(1,5), same as above except this time it starts from your first argument, 1. So you get 1 2 3 4 The 3rd argument is how each steps increases. By default it's 1. Let's pass a 2 and see what happens? range(1, 10, 2) --> 1 3 5 7 9. Starts from 1, goes up 2 each time, stops before 10. More on reddit.com

The break statement in Python brings control out of the loop. ... for letter in 'geeksforgeeks': if letter == 'e' or letter == 's': break print('Current Letter :', letter) ... Explanation: break statement is used to exit the loop prematurely when a specified condition is met. In this example, the loop breaks when the letter is either 'e' or 's', stopping further iteration.

The break statement exits the loop before reaching the print function. Python also has a continue statement that we can use to stop the current iteration of the loop and continue with the next. For example, if we find a specific name in the list, we can continue to the next name in the list instead of printing it.
