How To Remedy Code.Org Lesson 9 Half 7
On this last a part of Lesson 9, you may learn to use loops to repeat a set of directions a number of occasions. This can be a highly effective approach that can be utilized to resolve all kinds of issues. Let’s get began!
Step one is to create a loop. You are able to do this through the use of the `whereas` key phrase. The `whereas` key phrase takes a situation as its argument, and it’ll execute the loop physique so long as the situation is true. For instance, the next code creates a loop that can execute so long as the variable `i` is lower than 10:
“`
whereas i < 10:
# loop physique
i += 1
“`
The loop physique is the code that you just need to execute a number of occasions. On this instance, the loop physique merely increments the variable `i` by 1. You possibly can put any code you need contained in the loop physique, and it is going to be executed a number of occasions.
Loops can be utilized to resolve all kinds of issues. For instance, you should use loops to:
- Iterate over an inventory of things
- Repeat a process a sure variety of occasions
- Create patterns
Loops are a robust instrument that can be utilized to resolve all kinds of issues. Experiment with loops to see how you should use them to resolve your individual issues.
