Python Logic to Find All Unique Pairs in an Array

-
Image
 Here's the Python logic for finding all unique pairs in an array that sum up to a target value. Python Unique Pair Problem Write a Python function that finds all unique pairs in an array whose sum equals a target value. Avoid duplicates in the result. For example: Input: arr = [2, 4, 3, 5, 7, 8, 9] , target = 9 Output: [(2, 7), (4, 5)] Hints Use a set for tracking seen numbers. Check for complements efficiently. Example def find_unique_pairs(arr, target):     """     Finds all unique pairs in the array that sum up to the target value.     Parameters:     arr (list): The input array of integers.     target (int): The target sum value.     Returns:     list: A list of unique pairs that sum to the target value.     """     seen = set()     pairs = set()     for num in arr:         complement = target - num         if complement in seen:...

Why Learning Python is so useful?

Why Learning Python is so useful?

I have recently started learning Python. During my learning time, my friends have asked since you are interested in analytics why you need to learn Python. I explained the below reasons. This is one of the powerful languages after Java.

Python is similar to many programming languages that people generally know about: 

Python is very similar to JavaScript, Ruby, and PHP in many respects. 

Most programmers have a working knowledge of these programming languages and this makes it easier for programmers to learn Python. The basic features of these languages such as the use of arrays, anonymous functions, etc., are also present in Python. 

 
1. Python Machine Learning Libraries:

The variety of machine learning libraries that are available in Python is large.

One can choose between Scikitlearn, Keras, Theano, and Tensorflow. Many neural network libraries such as Keras, Theano, etc., are exclusively available in Python. So, if you want to do cutting edge machine learning work, you must know Python.

 
2. Python Handles Text Data: 

Unlike statistical software environments such as R, Python excels at handling text data. People who know Python can easily mine text corpus for useful insights. 


Python also provides support for Natural Language Processing through NLTK and sPacy
Python makes distributed computing very easy: Apache Spark has a Python API called PySpark. Using this piece of software, one can easily do distributed computing. PySpark has in recent times become the de-facto API for Spark. 


Extensive support for different data sources: It doesn’t matter if one needs to fetch data from an SQL server, a MongoDB database, or JSON data from some web API; Python can easily support all these data sources with a very clean and elegant syntax. 

3. Benefits of Learning Python

  • Learning Python has many advantages – it gives a user many skills, one can fetch data from different sources, create machine learning models, and do distributed computing seamlessly. 

  • For any programmer, learning Python will not be a difficult task. One can reap a lot of benefits by devoting time to learning Python.

Here's a quick resolution for import datetime Python error . The reason is your .py python script name and datetime  are the same. I'll show you how this error happens and its resolution.   Here's the Resolution for ImportError I've created a script called 'datetime.py.' to check whether the minute value is 'odd' or not. During the import of my python script, I got the import error cannot import name datetime. My Script: datetime.py My script's intention is to find whether the minute value is odd or not. Python Logic from datetime import datetime odds = [ 1 , 3 , 5 , 7 , 9 , 11 , 13 , 15 , 17 , 19 , 21 , 23 , 25 , 27 , 29 , 31 , 33 , 35 , 37 , 39 , 41 , 43 , 45 , 47 , 49 , 51 , 53 , 55 , 57 , 59 ] right_this_minute = datetime.today().minute if right_this_minute in odds: print ( "This minute seems a little odd." ) else : print ( "Not an odd minute." ) ImportError I have imported my datetime.py from Linux. It gives an error ...

SQL Query: 3 Methods for Calculating Cumulative SUM

-
Image
SQL provides various constructs for calculating cumulative sums, offering flexibility and efficiency in data analysis. In this article, we explore three distinct SQL queries that facilitate the computation of cumulative sums. Each query leverages different SQL constructs to achieve the desired outcome, catering to diverse analytical needs and preferences. Using Window Functions (e.g., PostgreSQL, SQL Server, Oracle) SELECT id, value, SUM(value) OVER (ORDER BY id) AS cumulative_sum  FROM your_table; This query uses the SUM() window function with the OVER clause to calculate the cumulative sum of the value column ordered by the id column. Using Subqueries (e.g., MySQL, SQLite): SELECT t1.id, t1.value, SUM(t2.value) AS cumulative_sum FROM your_table t1 JOIN your_table t2 ON t1.id >= t2.id GROUP BY t1.id, t1.value ORDER BY t1.id; This query uses a self-join to calculate the cumulative sum. It joins the table with itself, matching rows where the id in the first table is greater than...
