Why Pycharm clears the very first lines of the output from the console for long outputs?

Question

I wrote the code below. the very first line of the resulting output in the Pycharm console is different for the outputs that are not long with those that are long. I expected that it starts from "1" and scroll more and more for showing more output but it clears the very first lines by itself. :

code with the output that is not long (note the number "11"):

for x in range(1, 11):
   print(str(x), str(x * x), end=' ')
   print(str(x * x * x))

the first twelve lines of the console. the next lines are eliminated due to insignificancy (note it starts from the number "1"):

code with the output that is long (note the number "111111"):

for x in range(1, 111111):
   print(str(x), str(x * x), end=' ')
   print(str(x * x * x))

the very first line of its console (note it starts from the number "346" instead of "1"):

NOTE: I know I can see the rest of the results by pressing a key. my question is about the first line of the result, not the last line

Answer 1

That is because the console is only a certain number of lines long (looks like yours is 12) and you are just seeing the last 12 lines. If you scroll up you will see the rest... or you can print in a different way.

for example this:

for x in range(1, 111):
   print(str(x), str(x * x), end=' ')
   print(str(x * x * x))

   # pause every 10 lines
   if x % 10 == 0:
       input('press a key to continue')

the output:

1 1 1
