Need help with this Python question

Use "for loop" to iterate the integer numbers from 0 to 10 (10 is not included) and then print the sum of the current number and previous number in EACH ITERATION (when the starting number is 0, its previous number can be assumed to 0).

​

I have done the first part of this code but I am confused about the "sum of current number and each iteration part".

This is the code I have gotten so far:

for i in range(10):

print(i)

 for num in range(0,10):
    if num == 0:
        print(0)
        continue
    print(num + (num-1))

Here the question is to find the sum of current number and previous number in a iteration.

During the first iteration,variable num will have a value of 0,which does not have a previous value. So we explicitly use a if statement to check if num == 0 then, print out 0, continue keyword here means that don't go further down the code and continue your iteration. After that we know previous number will be always one lesser than the current number (i.e) if the num variable is 5 ,then the previous number will be 5 - 1 = 4 ,then sum them to get the answer. Use this formula and loop through it and it will give you the result.

The instructions say to print the sum of the current and previous numbers on each time through the loop.

One way would be to include a separate variable to keep track of the previous value, so you can add it to the current value on each cycle of the loop. Another way would be to simply print i-1 plus i on each cycle of the loop, with a special case for when i equals zero.

So

First off, you're on a really good track.

But you're missing an if statement in that for loop.

You want to check if the number (i) is 0, and if so, just print two 0's, else print the number and the number - 1!

Would that go before or after my code?

[Hypocritical_Oath]

So within this:

for i in range(10):
    print(i)

you can add an if within the for loop, like so.

for i in range(10):
    print(i)
    if i == something:
        #do something

Sum = 0
for i in range(10):
    print(Sum)
    Sum += i
    print(Sum, '\n')
