How to Create a Symmetric Array in Python: A Fun Logic Exercise

-
Image
 Here's a Python program that says to write a Symmetric array transformation. A top interview question. Symmetric Array Transformation Problem: Write a Python function that transforms a given array into a symmetric array by mirroring it around its center. For example: Input: [1, 2, 3] Output: [1, 2, 3, 2, 1] Hints: Use slicing for the reverse part. Concatenate the original array with its mirrored part. Example def symmetric_array(arr):     """     Transforms the input array into a symmetric array by mirroring it around its center.     Parameters:     arr (list): The input array.     Returns:     list: The symmetric array.     """     # Mirror the array by concatenating the original with its reverse (excluding the last element to avoid duplication)     return arr + arr[-2::-1] # Example usage input_array = [1, 2, 3] symmetric_result = symmetric_array(input_array) print("Input Array:", input_arr...

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']

** Process exited - Return Code: 0 **
Press Enter to exit terminal

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...
