loops in Python with examples and different problems

Python Loops

1. Python Loops

2. Python has two primitive loop commands: while  loops for  loops

3. The while Loop With the  while  loop we can execute a set of statements as long as a condition is true. Note:  remember to increment i , or else the loop will continue forever.

4. The  while  loop requires relevant variables to be ready, in this example we need to define an indexing variable,  i , which we set to 1.

5. The break Statement With the  break  statement we can stop the loop even if the while condition is true:

6. The continue Statement With the  continue  statement we can stop the current iteration, and continue with the next:

7. The else Statement With the  else  statement we can run a block of code once when the condition no longer is true:

8. Assignments Counting Up : Write a program that prints numbers from 1 to 10 using a while loop. Solution

9. Even Numbers : Create a program that prints all even numbers from 1 to 20 using a while loop. Solution

10. Countdown : Write a program that counts down from 10 to 1 and then prints "Blast off!" using a while loop.

11. Square Numbers : Develop a program that prints the square of numbers from 1 to 5 using a while loop. Solution

12. Character Printing : Create a program that prints each character of a given word entered by the user on a separate line using a while loop. Solution

13. Letter Counter : Write a program that counts the number of letters in a word entered by the user using a while loop. Solution

14. Positive Number Sum : Develop a program that asks the user for positive numbers and prints their sum. The program should stop when the user enters a negative number using a while loop. Solution

15. Power of Two : Create a program that prints the powers of 2 from 2^0 to 2^5 using a while loop. Solution

16. Vowel Counter : Write a program that counts the number of vowels (a, e, i , o, u) in a word entered by the user using a while loop. Solution
