What is "for loops" in python

Question

I was doing the python course and came across this. The first lesson made zero since though. Can someone explain? Pls.

Answer 1

It doesn't have to be i, it can be what you designate.
Example:
for sums in range(4):
print(sums +2)

I prefer i as it reminds me that it is an iterator

Answer 2

Example:
for i in range(4):
print(i +2)

So this means:- for the iteration in the range of (0 to 3), print the iterated value +2 each time.
0+2 =>2
1+2 =>3
2+2 =>4
3+2 =>5

Gavin Peacock asked the question because he was having difficulties understanding the lesson.

Answer 4

for loops use a var that keeps increment everytime it repeat.

Let say;
for x in range(2):
print(x, end = ',')
#output: 0,1,2,
Not necessarily use 'i', you can use any var. Also works with list;

list1 = [a, b, c]

for letter in list1:
print(letter, end = ',')
#letter is refer to elements in list1 and keep increment till the list end.
#output: a,b,c,

Answer 6

Thanks Rik Wittkopp but where does the "i" come from

Answer 7

Thanks Rik Wittkopp I really appreciate your help. But to clarify, "I" is just a variable and I could technically use "x"

Answer 8

Loops are use to repeat things x number of time, here x can be any value 2, 4, 5 up to whatever,

Imagine we want to repeat "hello, world 20 time", we can do this

for i in range(20):
print("hello, world!)

This will write "hello world 20 time",
