Unexpected twice output - Samo - Sep-29-2018 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 RE: Unexpected twice output - buran - Sep-29-2018 in each iteration you have 2 numbers in the range object import time Rysource = 1000 for _ in range(5): # print just first 5 results print('You will iterate over: {}'.format(list(range(Rysource, Rysource+101, 100)))) for Rysource in range(Rysource, Rysource+101, 100): print(Rysource)
RE: Unexpected twice output - gruntfutuk - Sep-29-2018 I'm really unclear on what you are trying to do beyond printing numbers in steps of 100 from a start point ... until you get bored and stop it. What the self referencing for loop is for, I have no idea. What's wrong with: from time import sleep Rysource = 1000 large_number = 9999 for counter in range(Rysource, large_number, 100): print(counter) sleep(5) If you really want it to go on for ever ... use a while loop, rather than a specific range in a for loop: from time import sleep Rysource = 1000 while True: print(Rysource) Rysource += 100 sleep(5) RE: Unexpected twice output - Samo - Sep-29-2018 Thanks. Quote:I'm really unclear on what you are trying to do beyond printing numbers in steps of 100 from a start point ... until you get bored and stop itThis was just an experiment, I wanted to print Rysource + 100 every certain amount of time until the end of the programm. Then I wanted to print something else meanwhile Rysource get printed. |
