New 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

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

August 14, 2021For 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

Python for loops are used for iterating over sequences like lists, tuples, strings and ranges. A for loop allows you to apply the same operation to every item within the loop. Using a for loop avoids the need to manually manage the index.

For-Loops — Python Numerical Methods
We use step as 2 in the range function to get the even indexes for list a. Also, a Python shortcut that is commonly used is the operator +=. In Python and many other programming languages, a statement like i += 1 is equivalent to i = i + 1 and same is for other operators as -=, *=, /=. Example Define a dictionary and loop through all the keys and values.

August 31, 2023 -
For the past 2 months I have been doing the Codecademy Python 3 course and last month I went into loops and functions and I was incredibly overwhelmed just like I was in Java. Functions are easy nothing special, at least yet, but loops are made me take that month break.
I know the theory of loops. I think I know what commands should be used where and when but for the love of god I can not write a simple loop, even after countless errors. Could anyone point me in the right direction? I really dont want to quit another language for the same reason.
Edit: a user pointed out that I need to elaborate on "simple loops". For example if I had a list and wanted to print a sentence as many times as the length of the list I know I would use len and range and have the print statement inside the loop but I can't implement it

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.

There are 3 kinds of loops that i can come up with that doesnt include itertools. 1: you have a loop that continues for x amount of iterations by being specific on how many iterations. This loop doesnt let you do anything with the values themself since they are all ints. Example: for i in range(5): (this will do the block of code 5 times starting from 0 and excluding the 5 and i will only be the integers 0 to 4) 2: you have a loop that will do the same as the first loop but this time its through all values in what you are looping through unless you specify on which values you want to loop through using indecies [start, stop, skip] if its a list or a string that is. Example: for my_value in my_list: (this will go through all the values in our list since we didnt specify what values to go through) 3: a condition based loop that will continue until the condition is met. Example of similar principal as the first loop: while i < 5: i+=1 (this will do the code block until i isnt less than 5, if you dont add to i it will never break since then i can never become not less than 5) So if you want to look through the actual values in something you have go with (2), if you want something to go a set number of times go with (1), if you want something to go until you tell it to stop do (3). If you want to know how to write better loops you should look into best practices for that, it doesnt mean like do tasks but just what to think about when making a loop and other things, there is ofc a bunch of mixed thoughts in what is the best and what not but being the best doesnt really mean anything, if it works it works. For your problem you dont need a loop, you already know len() so if you do print("hello")*len(my_list) it will print the msg as many times as the lenght of the list, but you can ofc use loops too, you can have that as excercise by knowing (1) and (3) and len and range.

You could show them this code for a better understanding:
Copystart = 1
length = 10
for i in range(start,start+length):
print(i)
There is also another feature that works like this, it's called slice.

Remind them that there is a reason the range function works this way. One helpful property of it is that the number of times the loop will run is equal to the second argument of range minus the first argument.
I think people get really hung up on this, but the fact is for loops in Python are very different than from C. In C, for loops are basically a wrapper around a while loop.
These two examples should help show the difference between how loops work in C versus python.
Copy# for(int x=1; x <= 10; x++)
x = 1
while x <= 10:
print(x)
x += 1
i = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] # range(1, 11)
for x in i:
print(i)
But honestly, the real problem here is that all loops and arrays are easier to understand and work with if they start at zero, not one. Please consider adjusting your examples to start at zero.
This way, if you want to loop 10 times, you use the number 10.
Copy # for(int x=0; x < 10; x++)
x = 0
while x < 10:
print(x)
x += 1
i = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] # range(10)
for x in i:
print(i)

November 21, 2025 - Other programming languages also implement for loops, but their syntax and capabilities can vary. Languages like C and Java use a more traditional approach, where the loop is controlled by initializing a variable, setting a loop continuation condition and defining the iteration step. This structure offers fine control over the loop but can be more verbose compared to Python's approach.
