Hello,

Can anyone please explain why the output calls the Evaluation statement before printing the series?

And what is the process to print the evaluation at the end?

Thank you.

----------------------------------------------

i=2000
while i <= 2100:
    i= i + 10
    print(i)
    if i == 2100:        
        print('task complete')

----------------------------------------------

The problem is that the program prints 'task complete' before the task is completed, because when i == 2100, the loop must run one more time because the loop says while i <= 2100.

Anyway, the 'task complete' thing should come after the loop.

i = 2000
while i <= 2100:
    i= i + 10
    print(i)
print('task complete')

Could throw a break statement in there.

i = 2000
while i <= 2100:
    i= i + 10
    print(i)
    if i == 2100:   
        print('task complete')
        break

A for loop is cleaner when you know exactly how many times the loop executes.

for i in range(2000, 2101, 10):
    print(i)
print('task complete')

Thank you, I have tried multiple combinations before posting it here, but don't know how I missed that, I feel so dumb

update-
I just noticed you omitted the == operator. I know its silly I am instructing and comparing the exact value. but can you do that with the == operator?

@menator01
hi, is the break operation really necessary? because it's already stopping, I mean its not an infinite loop.

update-

kudos, problem solved.
What magic is the break doing?? what did I miss?

@deanhystad

hi, I have learned the range (from, to, interval) function, but this was an experiment, and despite trying a many combination, I failed to get the desired result so I posted. actually I wanted to clear my conception. Still, thank you, if someone is looking will be helpful.
