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

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
