Why Quotation marks are used in python while doing a print command?. Also why don't we use them in print(2+2) why no quotes here

Question

Basically what is significance of them. I am very new to python I need to understand it so tell in simple language

Answer 1

quotation marks are used to enclose strings, not expressions (nor numbers, nor anything else ^^)

Answer 2

strings are kind of char lists:
"forty-two"

expressions are computations:
40+2
"forty"+"-"+"two"
22<=40 and 40<=42

usually expression contains variable names, or even function calls ^^
