For Loops

For loops are a specific statement for iteration. They are commonly used to repeat certain sections of code until a condition created for the loop is satisfied. For example, you could have a list of grocery items and you can set a condition such as filtering out dairy. Once you create the code, you can make it so it puts the dairy items in a list and that list will display all the dairy items that were filtered out. For loops can be specifically helpful in creating filters to organize large amounts of information.

I used code.org to create a program that filtered out different celebrities based on their profession. In order to do this, I made a for loop and created different filters such as actors or musicians to separate the different celebrities. This program would go through imported data sets and create lists of celebrities. Once filtered, I labeled each list and created a dropdown in order to see the different lists. I could click on each list to see which celebrities would fall under which profession. One thing I could improve on with this type of program could be overlapping professions. For example, person 1 would be an actor and a musician. However, person 2 would be only an actor but the two people would be on separate lists. This could create confusion and is extra work when I could create two separate lists and name them actor and musician respectively. Then I could include person 1 in both of those lists rather than having a separate list just to have both actors and musicians. Overall, for loops are extremely valuable in creating certain programs where a repeated segment of code is used several times throughout the program. For loops create an easy way to cut down on the amount of code you need to write, and is good at filtering large chunks of data in short periods of time.
