i doesn't make a loop. let's start with a couple of basics on loops (informal explanation): 1. loops allow the same instructions (code) to run over and over, usually until a condition is met which stops the loop. 2. your primary loops as a beginner are going to be "while" and "for" 2a. while loop - a while loop runs the code within it until something explicitly tells it to stop. basic example: #ask the user for the secret password string guess = str(input("Enter your password: ")) #create a loop that will allow user to guess #the password until letmein is entered while guess != "letmein": guess = str(input("Please try again: ")) #if isn't letmein, ask again #now out of loop, letmein was entered #congratulate user print("Good job! Password accepted!") 2b. for loops iterate over data / conditions example: #control variable is initiated in the loop #it doesn't have to be i, can be anything #i is just convention for i in range(0, 3): #let's tell the user current value of i print i the output would be: 0 1 2 all of this to say, i doesn't create loops. if you see it as part of a loop, that's just general convention to use the letter i hope this helps some
