This is my first time requesting a code review. This is code I wrote in Python to create a DNA sequence analyzer. This is for the Harvard CS50 course.
I was really hoping to get some constructive criticism on this code I finished for the DNA problem in Problem Set 6. This code passed all tests an...

That's not really an specific question about an specific problem, but I'd like to know how to improve this code, because I think that the main_func is just too big and I can not split it into other functions or classes. Also I want to know if I can or should use classes to make it cleaner. It's a...
I was wondering why we people don't use a generic interface instead of error type. You can see this pattern a lot in the Golang community:
func Division(a int, b int) (int, error) {
if b == 0 {
return 0, errors.New("divided by zero error")
}
return a / b, nil
}
error is not l...
i get an array of authors from json response and i have to display authors name in TextView(android) in proper format like =>Viraj, Chetan and George R. R. Martin
my code work fine, but it's a mess....
public class SeprateAuthors {
public static void main(String[] args) {
String[] authors0 = {"a
bool is_prime(int num)
{
if(num == 0 || num == 1 || (num != 2 && num % 2 == 0)
return false;
int sq = sqrt(num);
for(int i = 3; i <= sq; ++i, ++i)
if(num % i == 0)
return false;
return true;
}
We only need to check upto square ro...
I have written a simple expect script to tell me if a passwordless connection is set up. There is no 'expect' tag, so I hope using a 'shell' tag is acceptable.
I would appreciate any feedback.

puts "usage: test-nopass user server"
exit 1
}

I started reading Robert Martin's Clean Code. I'm trying to "translate" all his examples into Python, so I can understand them better since my domain on Python is greater than on Java. Please take a look at the following:

The Challenge: Given a string, return a string where each word is reversed individually without changing its position.
Thoughts and questions: Perhaps I was cheating the spirit of the challenge by using string builder? What do you think?
Complexity? Would the complexity be? I feel like it is O(n)...
It is a practice from the site edabit.com and you have to check if the input is valid. That is the original task:
Given an RGB(A) CSS color, determine whether its format is valid or not. Create a function that takes a string (e.g. "rgb(0, 0, 0)") and return True if it's format is correct, otherw...
I implemented the heaviest stone algorithm, but I am not sure about its time complexity. I'm doing sort which is O(nlogn), but it' inside a while loop.
Problem:
We have a collection of stones, each stone has a positive integer weight.
Each turn, we choose the two heaviest stones and smash them to...
I'm looking forward to increment a code-interview challange I was given a few weeks past.
Since the code has some dependencies and became quite large, I will let it be posted on Github in this link

This code is designed for my 30led neopixel clock, the reason for not using the ds3231 library is due to the fact that I use codebender to download programs to my arduino, I wanted some critique on things that could be improved and any glaring problems that should be fixed.
Thanks!

I have a list of 2,888,991 channel objects. Each object has a name and a sample rate. I am trying to put them into a QTreeView. Each channel name is split on ':' '-' and '_'. If the name is H1:IOP-LSC0_DCU_ID and the sample rate is 16.0 then it should go into the tree as:
H1
IOP
LSC0
