How can i get many input from user in sololearn when i dont know the number if input?!

Answer 1

You mean like
While 1:
input()

Here the number of input is unknown so
it will give EOF error on sololearn ,so you can't

Answer 2

If you are asking like real time execution, then it is not possible here.. Because SoloLearn takes all the inputs at once only and also before start of execution...

Edit:
For additional info, if you don't know,
See this, for how SoloLearn handle input :
