 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 ...

Here's a simple bash recursive function. To write it, you can use JavaScript and other scripting languages. Below is the example that shows you how to write a recursive function in the bash shell. Recursive function Precisely, calling the same function within it is called the Recursive function. We call itself and its contents.  Moreover, the recursive functions go in the loop due to self-calling. While writing the code, ensure it has a condition that breaks the loop. Recursive logic #!/bin/bash for ((i = 1; i < 65; i++)) { ((arr[i - 1] = i)) } i = 1; key = 8 function linear_search { echo "Element value: ${arr[$i-1]}" if ((arr[i - 1] == key)) then echo "Linear search found $key on attempt $i" return 0 => it breaks the loop else ((i++)) linear_search = > Calling th same script fi } linear_search = > Calling the same script Output Here is the dissection of the output. Displayed the array's elements until match-condition occurs. In the end, a displa...

Here's a bash script to generate a random number. You can use this logic to generate a random number, and it is useful for AWS engineers. Random number Script - Here's sample logic to get a random number RANDOM=$$ # Set the seed to the PID of the script UPPER_LIMIT=$1 RANDOM_NUMBER=$(($RANDOM % $UPPER_LIMIT + 1)) echo "$RANDOM_NUMBER" If you select UPPER_LIMIT as 100, then the result would be a pseudo-random number between 1 and 100. Her is the output after executing the script Related posts Structured Vs. Un-structured data
