Left to right precedence is fine. But there are other rules also, such as 2 pow (3 pow 2) You cannot calculate power of 2 until 3 pow 2 evaluates to a number. So, it needs to be evaluated first.

bit confused there @Vega 8**2 is 64 what happenens in the print is as follows: let's define two events, a and b a is 3**2 b is 2**a b a 2**(3**2) a is evaluated first to give us 3 to the power of 2 and returns 9 a=3**2=9 then b is evaluated as 2 to the power of a ro give us 2 to the power of 9 which returns as 512 b=2**9=512

"Operators in the same box group left to right (except for exponentiation, which groups from right to left)." https://docs.python.org/3/reference/expressions.html#operator-precedence That means, a**b**c evaluates to a**(b**c).
