[FIXED] Update only two lines in print inside jupyter notebbok

Issue

I want to print only two lines in my cycles, I started with the following:

import time

for i in range(10):
    time.sleep(0.5)
    for j in range(10):
        time.sleep(0.5)
        print('Index1:', i)
        print('Index2:', j)

I tried different combinations of \r, \n, flush=True etc. at the beginning and end of print, but wasn't successful((

What I'd like to see is as in the GIF of accepted answer here

I tried those code, but it didn't help, maybe because my OS is Windows or I use jupyter notebook, I have no idea((

Solution

In Jupyter Notebook, you can clear current cell output using IPython.display.clear_output(wait=True)

In terminal, similiar behaviour can be achieved using ANSI escape codes, as in the following snippet:

import time

n = 15
for i in range(n):
    print(f"{i}s passed")
    print(f"{n-i}s remaining")
    time.sleep(1)
    print("\u001b[2A", end="") #ANSI escape code for cursor up 2 lines
