 Expression 1 is evaluated as:
2**9, which is equal to 512. Expression 2 is
evaluated as 8**2, which is equal to 64. The
last expression is evaluated as 2**(3**2).
This is because the associativity of **
operator is from right to left. Hence the result
of the third expression is 512.

 the above expressions are evaluated as: 2/2, 8/2, which is equal to (1.0, 4.0).

 The expression shown above is
evaluated as: 2+9*(36-8)/10, which simplifies
to give 2+9*(2.8), which is equal to
2+25.2 =27.2.
Hence the result of this expression is 27.2.

 the expressions are evaluated as: 4%3 and 6//2 respectively. this results in the answer (1,3). this is because the associativity of both of the expressions shown above is left to right.

 the above expression is an example of explicit conversion. it is evaluated as: float(4+int(2.39)%2) = float(4+2%2) = float(4+0) = 4.0. hence the result of this expression is 4.0.

 The order of precedence is: **,
//, +. The expression 4+2**5//10 is evaluated
as 4+32//10, which is equal to 4+3 = 7. Hence
the result of the expression shown above is 7.

 the value of the expression (2**2)**3 = 4**3 = 64. when the expression 2**2**3 is evaluated in python, we get the result as 256, because this expression is evaluated as 2**(2**3). this is because the associativity of exponentiation operator (**) is from right to left and not from left to right.

 the result of the expression shown will be 1011. this is because we have not specified the base in this expression.

 the expression int(1011,2) results in an error. had we written this expression as int(‘1011’,2), then there would not be an error.

 the ^ operator represent bitwise xor operation. &: bitwise and,
