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...

In Python, you can assign values to the variables. This post tells you how to assign values to multiple variables. It is common assigning values in any programming language. But Python simplifies your job by introducing this technic. Here is  Python For Loop Tricky Example . Python Assigning the Values At once. a = 1 b = 1 c = 1 d = 1 or, you can assign simultaneously as; a=b=c=d=1 Python Assigning Multiple Values at Once The other way you can assign as; a, b, c, d = 10, 1, 3.5, 'Srini' From the above, you can understand as below: The '10' assigns to a. The '1' assigns to b. The '3.5' assigns to  c. Then 'Srini' to d.  References Python Basics Variable Assignment
