Iterate 10 to 0 using for loop, do the same using while loop. Write a loop that makes seven calls to print(), so we get on the output the following triangle: ... # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # ... 0 x 0 = 0 1 x 1 = 1 2 x 2 = 4 3 x 3 = 9 4 x 4 = 16 5 x 5 = 25 6 x 6 = 36 7 x 7 = 49 8 x 8 = 64 9 x 9 = 81 10 x 10 = 100 · Iterate through the list, ['Python', 'Numpy','Pandas','Django', 'Flask'] using a for loop and print out the items.

October 2, 2020Nested for loops - bad practice? How to avoid?
Performance-wise, nesting loops increases execution time exponentially. You should look at unrolling loops and precalculating values that won't change during each iteration.
Otherwise, they are sometimes necessary.

December 4, 2015Best way to learn loops in python & make it stick?
You have to solve problems that require repetition If you have to do something against every item in a list, you use a for loop. for item in some_list: # do something with item If you have to do something until a condition ends you use a while loop. while some_condition: # do something More on reddit.com

May 12, 2024For loops and while loops
I get what you are saying :) I need a lot of practice for stuff to stick. When I was learning conditionals and looping, the best advice I got was to start with some practice problems, then make up similar problems with my own data and scenarios. For example, you could write a program to loop through a list of addresses and have it return some information about each entry. Or, you could write a program to take keyboard input and keep printing some result until you enter 'N' (the while loop in action). We were also told to try to solve the problems without using while or for loops to help motivate why you would want them in the first place. That really helped solidify the concepts for me, because you can write code without the loops, but it gets long and tedious... Btw, another link I used was https://www.practicepython.org/ .

How do I use a for loop in Python?
To use a for loop in Python, you can use the "for" keyword followed by a variable name, the "in" keyword, and then the sequence you want to iterate over. For example: my_list = [1, 2, 3] for num in my_list: print(num).

Can I use a for loop with a dictionary in Python?
Yes, you can use a for loop with a dictionary in Python. By default, a for loop will iterate over the keys of a dictionary. For example: my_dict = {"a": 1, "b": 2, "c": 3} for key in my_dict: print(key, my_dict[key]) This will print each key-value pair in the dictionary, one at a time.

October 2, 2020 -
I'm looking for projects that can help me practice for and while loops:
So far, I have mastered if statements, operators, and all the simple stuff, however, I have been struggling with loops for some time. I figure some practice projects could help me get the hang of it.

It's hard to imagine any kind of program that wouldn't contain a loop; it's a pretty essential concept in the programmer's toolkit.
So really any project will make you write for loops. (Don't worry about while, it's actually used quite a bit less in Python.)
But I think better than practice is understanding. If you understand what for does then the conditions under which you should use it are pretty obvious.
