The backgroud
This two funtions are used to create loop that inside is a code that you wish to repeat it self. The question is if they are the same how to choose between them. I will explain each one and then teach you how to choose between them.
For
This funtion repeats itself only the times that you indicate or until it condition is not longer true.
Lets see this example:
This code for each letter in the word Python will run the code.
Let’s see what it does.
While
This funtion repeats itself until it make false it’s value.
This is the logic that While follows:
The next Example will make it clear:
This program will run each time until count be 9. Lets see what it does:
Which one I use?
The use of each one depends on what you need. Lets see if you know how many times the user will put the correct answer use for but if you don’t know how many times you can use a infinite while.
The material use can be seen here:
