Python for loop with range, can we change iterators value inside for loop

Question

Python loop for iterator following is code snippet

sum = 0
for i in range(10):
i = I + 3
sum += 3
print (sum)

It sums up the 10 number from offset 3

Why it's not affect the updation of iterator to loop for lesser number of iterations since I is updated by adding three(3)

Answer:
75

3 + 4 + 5 + ... + 12 = 75

Answer 1

idk much about python but u can think it like this
if u do list instead of range
eg:
a = [2, 3, 2 ,3]
for i in a:
print(i)
what u print is the value of list in each iteration(i = a[currentindex])
so even if u increase i inside the loop, the index still not change, cause i is the value of the range
im not good at explaining but hope u understand what i mean

Answer 2

i dont really know..but since list(range(10)) return that, probably..let just hope some python expert to answer and clear this thing up for us😂

Answer 3

yes, range return a list (a generator in python3+) and you iterate over values: that's why changing 'iterator' variable (i) inside the loop has no effect on next iteration ;)

Thanks
Looks like it is a new one

Thanks for quick reply

can I assume that
range(10) as
[0,1,2,3,4,5,6,7,8,9] list
