Unexpected twice output

[Samo]

Hi guys! given that I'm new to Python and coding in general ...

I have the following code, every 5 seconds I want to print Rysource +100, but the output, as you can see, is printed double:

import time

Rysource = 1000

while True:
    for Rysource in range(Rysource, Rysource+101, 100):
        print(Rysource)
    time.sleep(5)

OUTPUT:
1000
1100
1100
1200
1200
1300
1300
1400


Basically it starts with: 1000,1100. After 5 seconds prints: 1100,1200. After 5 seconds prints: 1200,1300
And so on...
How can i print something like this:

OUTPUT:
1000
1100
1200
1300
1400

I hope this is clear and thank you
