Given a number, return a list of integer with python function.
In this chapter, we are given a number and we need to return a list of integer based on that number, for example, number 3 will return a list of [1,2,3].
We will first create an empty array, then we will loop through that number and push the new number (count + 1) into that empty list.
def monkey_count(n): li =  for i in range(n): li.append(i+1) return li
There is one easy solution as compared to the above, let me know in the comment box below this post.
In this snippet, we are going to create a python method to reverse the order of a number. This is one of the questions on Codewars. If you enter -123 into the method you will get -321. If you enter 1000 into the method you will get 1. Below is the entire solution.
def reverse_number(n): num_list = list(str(n)) num_list.reverse() if "-" in num_list: num_list.pop(len(num_list)-1) num_list.insert(0, "-") return int("".join(num_list))
If you do follow my website you know that I always write simple python code and post them here, but starting from the next article, I will stop posting python code for a while and start to talk about my python journey and the cool software which is related to python. I hope you will appreciate this new style of writing and thus will make learning python for everyone a lot more fun than just staring at the boring and sometimes long python snippet.

If you have any solution for this problem do comment below.
In this example we are going to create a function which will count the number of occurrences of each character and return it as a list of tuples in order of appearance. For example,
ordered_count("abracadabra") == [('a', 5), ('b', 2), ('r', 2), ('c', 1), ('d', 1)]
The above is a 7 kyu question on CodeWars, this is the only question I can solve today after the first two fail attempts.
I am supposed to start the Blender project today but because I want to write a post for your people I have spent nearly an hour and a half working on those three python questions on CodeWars, I hope you people will really appreciate my effort and will share this post to help this website to grown.
def ordered_count(input): already =  input_list = list(input) return_list =  for word in input_list: if(word not in already): return_list.append((word, input_list.count(word))) already.append(word) return return_list
The solution above is short and solid, hope you like it.
Hello people, this will be the last article which we will solve a simple question in CodeWars, in the next chapter we will start our next python project. In this chapter, we will solve one of the questions in CodeWars and the question goes like this.
Given a number, find the reverse order’s numbers of that number until one and put them in a list. For example, number 6 will make the method to return a list of reverse numbers up until 1, [6,5,4,3,2,1]. Below is the solution.
def reverse_seq(n): list_ =  while(n > 0): list_.append(n) n -= 1 return list_
So we have solved that simple question on CodeWars and we have received 2 kyu from our hard work. With that, we have temporary concluded the question solving chapter and will start our next python project in the next chapter.
Before we start our new python project here is another solution for one of the python’s question on codewars. In this example, we need to create a method which will accept a number and returns a list consists of a pair of a number and power that are equal to that input number. For example, the input number is 9, then the number and it’s power which is equals to that input number is [3, 2] because 3 * 3 = 9. If there is no number and power that match the input value then None will be returned. Here is the solution to the above mentioned question.
def isPP(power): for num in range(1, power): for po in range(2, power): if(num ** po == power): return [num, po] return None
The above method is only suitable to solve a number input which is below 1800, the program will become freeze if the number goes beyond that value (depends on the processing power of your own computer). Well, hope you like this quick solution, in the next chapter we will begin our project.
