They identifies cells in an iPython/Jupyter notebook. Cells enclosing input prompts use In[x], where x is just a serial number you can use to refer to previous inputs. Out[x] is the cell containing the output of the corresponding In cell.
Your example shows an input of 3 + 2, following by its value. print(3+2) is likewise an input, but the 5 is simply text written to standard output. As the input expression had the value None (the return value of the print function), no output cell was created.
I believe you are typing this out in a Jupyter Notebook or a Python Editor. In and Out here means Input and Output.
