I was looking this week on the codenight forum go topic and there was a hot argument about using pure sql or using orm for handling models and database things what is your idea about this 😄

I was crazy and thinking to make a library that can make github as a storage for syncing user data 😄 what do you think?🙄

Hey people do you want to join developers community arround the world here is one on slack and it is all about go I will try to find others that are more general. Since these kind of networks are really crucial for your career as software developer I highly recommend you to really join them and I will send much more like this soon

Ever missed contests on many platform and wondered how to get them. There is a good solution for me which gives you all of the upcoming and previous contests on every competitive programming platform. It is called CodeClock and it lets u add the contest that you want to your calendar and you will never miss any again

Have You Ever Got Stuck Comparing Values in Python Sorting? Meet cmp_to_key!

If you've been solving problems on LeetCode or coding challenges in general, you’ve probably faced a situation where you need custom sorting logic—like sorting based on multiple conditions. This is where Python's cmp_to_key comes in, and it can save the day!What is cmp_to_key?Imagine you have a comparison function that says,

If this value is smaller than that, return -1; if they're equal, return 0; if it's bigger, return 1.

This is called a comparison function (cmp). But modern Python sorting methods like sorted() or .sort() use a key function instead.So how do you use your custom cmp function with sorted()? Simple—convert it using cmp_to_key!

Example:

Sorting Strings by Length, Then AlphabeticallyLet’s say you need to sort a list of words. First, by length. If two words have the same length, you sort them alphabetically.

from functools import cmp_to_key

def compare(a, b):
if len(a) == len(b):
return -1 if a < b else 1 # Compare alphabetically if lengths are equal
return len(a) - len(b) # Compare by length

words = ["apple", "bat", "banana", "pie", "cat"]
sorted_words = sorted(words, key=cmp_to_key(compare))

print(sorted_words) # Output: ['bat', 'cat', 'pie', 'apple', 'banana']

Without cmp_to_key, writing such sorting logic can get messy. But here, you just write your comparison function, and cmp_to_key handles the rest.Example: Custom Sorting NumbersLet’s sort a list of numbers where we want even numbers first, sorted in descending order, and odd numbers second, sorted in ascending order.

def custom_compare(a, b):
if a % 2 == b % 2: # Both even or both odd
return b - a if a % 2 == 0 else a - b # Descending for evens, ascending for odds
return -1 if a % 2 == 0 else 1 # Even before odd

numbers = [3, 1, 4, 10, 5, 6, 7]
sorted_numbers = sorted(numbers, key=cmp_to_key(custom_compare))

print(sorted_numbers) # Output: [10, 6, 4, 1, 3, 5, 7]
How Does It Work?

If a should come before b, return -1.If a and b are equal, return 0.If a should come after b, return 1.

Why I am seeing airdrop story everywhere 😂

functools is crazy surprising me again with accumulate a function for calculating the prefix sum of an array

But still the main python submission on codeforces 😭
