Why do I need to give print command for mathematical operations?

Question

In Simple operation chapter, it is said that python can calculate directly.

"Python has the capability of carrying out calculations.
Enter a calculation directly into the Python console, and it will output the answer."

There was no result when I entered 2+2 in the code playground. However print(2+2) gives output 4.
But print("2+2") gives 2+2.

Answer 1

in a proper IDE (not the solo playground) entering 2+2 does result in 4

"2+2" is a string, so it will always be printed as 2+2 onto the screen. it isn't 2 numbers with an operator in the middle, it is basically words that look like 2+2

Answer 2
