The difference between "+ =" and "= +"?

Question

So, I have a simple piece of code that outputs integers 1-10:

i = 0
while i < 10:
        i += 1
        print(i)

Then, if you just change one statement to line 3, it produces an infinite number of 1 integers (which I understand why it does this). Why is there no syntax error when starting this second program? Wouldn't that cause a syntax error if the assignment operator is followed by the addition operator?

i = 0
while i < 10:
        i =+ 1
        print(i)

Answer 1

i+=1matches with i=i+1, whereas it i=+1means only i=(+1).

Answer 2

Answer 3

i =+ 1 i = +1 i = 1.

Answer 4

x=+1 : x=(+1)
x+=1 : x=x+1

+ () .

Answer 5

There is no syntax error because the expression i =+ 1matches i = (+1)and is +1perfectly legal. This is a unary operator, not an addition operator.
