Operators are special symbols that represent computations like addition and multiplication. The values the operator is applied to are called operands.
** perform addition, subtraction, multiplication, division, and exponentiation, as in the following examples:
20+32 hour-1 hour*60+minute minute/60 5**2 (5+9)*(15-7)
There has been a change in the division operator between Python 2.x and Python 3.x. In Python 3.x, the result of this division is a floating point result:
>>> minute = 59 >>> minute/60 0.9833333333333333
The division operator in Python 2.0 would divide two integers and truncate the result to an integer:
>>> minute = 59 >>> minute/60 0
To obtain the same answer in Python 3.0 use floored ( // integer) division.
>>> minute = 59 >>> minute//60 0
In Python 3.0 integer division functions much more as you would expect if you entered the expression on a calculator.
