Python Number Programs Using While Loop: Step-by-Step Guide
Introduction Number-based problems are essential for improving programming logic. Using Python's while loop, we can solve different types of problems involving divisibility, counting, and special numbers. This article demonstrates step-by-step solutions using simple logic and structured code. Basic Practice 1. Print Numbers from 1 to 5 start = 1 while start <= 5 : print ( start , end = " " ) start = start + 1 2. Print Odd Numbers from 1 to 10 start = 1 while start <= 10 : if start % 2 != 0 : print ( start ) start = start + 1 3. Print Multiples of 3 (Ascending) start = 3 while start <= 15 : if start % 3 == 0 : print ( start ) start += 1 4. Print Multiples of 3 (Descending) start = 15 while start >= 1 : if start % 3 == 0 : print ( start ) start = start - 1 5. Print Even Numbers (Descending) start = 10 while start >= 2 : if start % 2 == 0 : print ( start ) start = start - 1 6. Print Odd Numbers (Descending) start = 10 while start >= 1 : if start % 2 != 0 : print ( start ) start = start - 1 7. Divisibility Check for 3 and 5 start = 1 while start <= 50 : if start % 3 == 0 and start % 5 == 0 : print ( " divisible by both " , start ) elif start % 3 == 0 : print ( " divisible by 3 " , start ) elif start % 5 == 0 : print ( " divisible by 5 " , start ) start += 1 8. Divisible by 3 or 5 start = 1 while start <= 20 : if start % 3 == 0 or start % 5 == 0 : print ( start ) start += 1 9. Finding Divisors of a Number num = 12 i = 1 while i <= num : if num % i == 0 : print ( i ) i += 1 10. Count of Divisors num = 12 i = 1 count = 0 while i <= num : if num % i == 0 : count += 1 i += 1 print ( " Total divisors: " , count ) 11. Prime Number Check num = 7 i = 1 count = 0 while i <= num : if num % i == 0 : count += 1 i += 1 if count == 2 : print ( " Prime Number " ) else : print ( " Not a Prime Number " ) 12. Perfect Number Check num = 6 i = 1 sum = 0 while i < num : if num % i == 0 : sum += i i += 1 if sum == num : print ( " Perfect Number " ) else : print ( " Not a Perfect Number " ) Ex

AWS Replaces Fat-Tree Data Center Networks with Random Graph Theory, Cutting Routers by 69%
AWS disclosed that Resilient Network Graphs, a flat network architecture based on quasi-random graph theory, is now the default for most new data center builds. The design replaces fat-tree hierarchies with direct ToR-to-ToR mesh connections using passive optical ShuffleBoxes, cutting routers by 69%, boosting throughput by 33%, and reducing network power consumption by 40%.

Article: The Schema Proliferation Problem in Kafka and Flink Pipelines: How to Solve It
Schema proliferation builds slowly and gets expensive fast. One schema per event type feels right until there are ten tables, union queries spanning all of them, and a single field rename touching every schema. Discriminator-based schema consolidation collapses that to two tables, turning multi-table unions into a single query, while new variants are additive and don't break existing consumers.
