15 Python Tips : How to Write Code Effectively

-

 Here are some Python tips to keep in mind that will help you write clean, efficient, and bug-free code.     Python Tips for Effective Coding 1. Code Readability and PEP 8  Always aim for clean and readable code by following PEP 8 guidelines.  Use meaningful variable names, avoid excessively long lines (stick to 79 characters), and organize imports properly. 2. Use List Comprehensions List comprehensions are concise and often faster than regular for-loops. Example: squares = [x**2 for x in range(10)] instead of creating an empty list and appending each square value. 3. Take Advantage of Python’s Built-in Libraries  Libraries like itertools, collections, math, and datetime provide powerful functions and data structures that can simplify your code.   For example, collections.Counter can quickly count elements in a list, and itertools.chain can flatten nested lists. 4. Use enumerate Instead of Range     When you need both the index and the value in a loop, enumerate is a more Pyth

What is Elastic Nature in Cloud Computing

-
Natural clouds are indeed elastic, expanding and contracting based on the force of the winds carrying them. The cloud is similarly elastic, expanding and shrinking based on resource usage and cloud tenant resource demands. The physical resources (computing, storage, networking, etc.) deployed within the data center or across data centers and bundled as a single cloud usually do not change that fast.
This elastic nature, therefore, is something that is built into the cloud at the software stack level, not the hardware.
Best cloud computing example: The classic promise of the cloud is to make compute resources available on demand, which means that theoretically, a cloud should be able to scale as a business grows and shrink as the demand diminishes. Consider here, for example, Amazon.com during Black Friday. There's a spike in inbound traffic, which translates into more memory consumption, increased network density, and increased compute resource utilization. If Amazon.com had, let's say, 5 servers and each server could handle up to 100 users at a time, the whole deployment would have peak service capacity of 500 users. During the holiday season, there's an influx of 1,000 users, which is double the capacity of what the current deployment can handle.

If Amazon were smart, it would have set up 5 additional (or maybe 10) servers within its data center in anticipation of the holiday season spike. This would mean physically provisioning 5 or 10 machines, setting them up, and connecting with the current deployment of 5 servers. Once the season is over and the traffic is back to normal, Amazon doesn't really need those additional 5 to 10 servers it brought in before the season. So either they stay within the data center sitting idle and incurring additional cost or they can be rented to someone else.

What we just described is what a typical deployment looked like pre-cloud. There was unnecessary physical interaction and manual provisioning of physical resources. This is inefficient and something that cannot be linearly scaled up. Imagine doing this with millions of users and hundreds or even thousands of servers. Needless to say, it would be a mess. This manual provisioning is not only inefficient, it's also financially infeasible for startups because it requires investing significant capital in setting up or co-locating to a data center and dedicated personnel who can manually handle the provisioning.

This is what the cloud has replaced. It has enabled small, medium, and large teams and enterprises to provision and then decommission compute, network, and memory resources, all of which are physical, in an automated way, which means that you can now scale up your resources just in time to serve the traffic spike and then wind down the additional provisioned resources, effectively just paying for the time that your application served the spike with increased resources. This automated resource allocation and deallocation is what makes a cloud elastic.

How to Fix datetime Import Error in Python Quickly

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

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 or

What is placeholder in Python? The purpose of it is to mask the variable that you don't want to use in a function. In python, y ou can call the underscore ( _ ) operator placeholder. Below, you'll find how to use single and double placeholders in a function. What is placeholder in python The purpose of placeholder in Python is to mask variables that you don't want to use in a function. So that your code will be readable. Moreover, in future, if you want to use those variables you can replace the placeholders with the names you want. In This Page You'll know in three steps how to use placeholder correctly. Creating a function Logic to use single placeholder Logic to use two placeholders 1. Creating a function. def function_that_returns_multiple_values(x):        return x*2, x*3, x+1        for i in range(0,5):             square, cube, added_one = function_that_returns_multiple_values(i)             print(square, cube) Here, in print, it returns two variables.
