When you're programming, it's really important to know how different kinds of loops can change the way your program works.

Loops are special tools that allow us to repeat actions without writing the same code again and again. Let’s explore the main types of loops and how they shape your code.

Types of Loops

1. For Loop:

   • This loop works best when you know exactly how many times you want to repeat something.
   • For example, if you want to print the numbers from 1 to 10, a for loop makes this easy:

     for i in range(1, 11):
         print(i)
     

   • The flow is clear: you start, repeat a set number of times, and then finish.

2. While Loop:

   • This loop is useful when you want to keep repeating until something specific happens.
   • For example, if you want to keep asking a user for an answer until they give a correct one, a while loop is just right:

     while True:
         response = input("Enter 'yes' to continue: ")
         if response == 'yes':
             break
     

   • Here, the flow can change based on what the user says.

3. Do-While Loop:

   • This loop is similar to ones used in other programming languages (like Java or C). It makes sure the action happens at least once, no matter what.
   • The difference is that you check the condition after you do the action.
   • This is helpful when you want to make sure something happens at least one time.

Conclusion

To sum it up, the type of loop you pick affects how your program runs. A for loop is simple and direct, while a while loop allows for more interactive experiences. Knowing these differences will help you write better code in your projects! Happy coding!
