Carefully notice, when you assign an expression to a name

Q. In front of Python prompt, i.e., In [] prompt, type following expressions one by one, by pressing return key after every expression, e.g.,

NOTE :- In []: stands for input command and Out | stands for output here Python shows the output.

In[1] : 6*3

It will show output lines starting with Out[ ] :, e.g.:

Out [2] : 18

[Carefully notice, when you assign an expression to a name e.g., P = 2 + 3 in front of prompt In[ ], does Python display anything? When does Python display and when not?]
