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

Relative Vs. Absolute Path in Linux: Top Differences

-
 Here's the difference between the relative and absolute paths in Linux. Many a time, the programmer needs to trade in these paths. Here're simple ideas on how you can differentiate.

Top differences between absolute and relative paths

Absolute Vs. Relative path


These are the differences between Absolute and Relative path in Linux.

Absolute Path


$ cd /usr/lib

$ cd /usr/lib pwd

See this path (linux#1/usr/lib), when you give PWD, it gives a full path from the root level. This is called absolute or full path.

Think of the absolute pathname as being the complete mailing address for a package that the postal service will deliver to your next-door neighbor.

Relative Path


$ cd usr
$ /user cd lib
$ /usr/lib pwd

$ linux#1/usr/lib ==> Going step by step and achieving.

$ linux#1/usr/lib cd ../../ ==> This is the method of going back step by step.

$ linux#1 ==> This is root level directory

You are currently in the lib directory. So relative path nothing but complete information of all the mother directories.

Here, for lib, the usr is the mother directory. In simple terms, it is a step-by-step way and to reach your target directory. You might aware the .. (double dots), means you'll go to the mother of the current directory.

Think of the relative directory name as giving the postal carrier directions from your house to the one next door so that the carrier can deliver the package.

Command to got to Home directory


$ linux#1/usr/lib

You currently in the 'lib' directory.

$ cd

$ linux#1 ==> This is your home directory.

Notes: If you give cd without any arguments, it goes to home directory.

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.
