Python: Built-in Functions vs. For & If Loops – 5 Programs Explained

Image
Python’s built-in functions make coding fast and efficient. But understanding how they work under the hood is crucial to mastering Python. This post shows five Python tasks, each implemented in two ways: Using built-in functions Using for loops and if statements ✅ 1. Sum of a List ✅ Using Built-in Function: numbers = [ 10 , 20 , 30 , 40 ] total = sum (numbers) print ( "Sum:" , total) 🔁 Using For Loop: numbers = [ 10 , 20 , 30 , 40 ] total = 0 for num in numbers: total += num print ( "Sum:" , total) ✅ 2. Find Maximum Value ✅ Using Built-in Function: values = [ 3 , 18 , 7 , 24 , 11 ] maximum = max (values) print ( "Max:" , maximum) 🔁 Using For and If: values = [ 3 , 18 , 7 , 24 , 11 ] maximum = values[ 0 ] for val in values: if val > maximum: maximum = val print ( "Max:" , maximum) ✅ 3. Count Vowels in a String ✅ Using Built-ins: text = "hello world" vowel_count = sum ( 1 for ch in text if ch i...

Here is Sample Logic to get Random numbers in Bash

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
