Have you noticed this?

Question

x=2
print(2)
output-->2
print(x+=2)
output-->(2+2)=4
now x is 4...
Print(x+2)
output-->6
this process(x+=a number) rendees the result to be x..
now,
x=2
print(x)
output-->2
print(x+2)
output-->4
here x still remains 2
print(x+3)
output-->(2+3)=5
so note the difference between (x+=y) and (x+y)..

Answer 1

The difference between this is crystal clear. += is an assignment operator (x+=2 same as x=x+2) but + is just a simple addition operator. Simply, x=x+2 (or x+=2) is a STATEMENT which PERFORMS AN ACTION while x+2 alone is an EXPRESSION which simply EVALUATES TO A VALUE 😊

Answer 2

yes, the "+=" operator is different with just "+"..

x += y is equal x = x + y, so the value of x, will be replace with the result of the operation.. and this applies to subtraction, multiplication, etc....
