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

Python Split String: Techniques and Best Practices

-
Here is an example for splitting a string in Python. The functions you need are strip and split to split string, or text. 

python split string


Here's the string taken for split

My task is I want to split address string. Historically, the address is lengthy. It contains the door number, floor number, street number, and street name.

Rama Krishna 20/3 ABC street EFG Nagar US 234567

How to Split a string

The python split string works in two steps. The first step is to use strip function, which removes both leading and trailing spaces. Next, use the the split function, which splits the input string, or text into a list.

Python program

user_address = input("Enter an address")

if user_address.strip(): #check that string is not empty (after removing leading
#and trailing spaces)
    print("Your address is " + user_address)
split_address = user_address.split()
print(split_address)

Output

Interactively, it asks the user to enter the address. After the code runs, the address splits into separate strings in a list.

Enter an address
Rama Krishna 20/3 ABC street EFG Nagar US 234567

Your address is Rama Krishna 20/3 ABC street EFG Nagar US 234567
['Rama', 'Krishna', '20/3', 'ABC', 'street', 'EFG', 'Nagar', 'US', '234567']

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.
