Python 3 - Operators Precedence Example
The following table lists all operators from highest precedence to the lowest.
Sr.No. | Operator & Description |
---|---|
1 | ** Exponentiation (raise to the power) |
2 | ~ + - complement, unary plus and minus (method names for the last two are +@ and -@) |
3 | * / % // Multiply, divide, modulo and floor division |
4 | + - Addition and subtraction |
5 | >> << Right and left bitwise shift |
6 | & Bitwise 'AND' |
7 | ^ | Bitwise exclusive `OR' and regular `OR' |
8 | <= < > >= Comparison operators |
9 | <> == != Equality operators |
10 | = %= /= //= -= += *= **= Assignment operators |
11 | is is not Identity operators |
12 | in not in Membership operators |
13 | not or and Logical operators |
Operator precedence affects the evaluation of an expression.
For example, x = 7 + 3 * 2; here, x is assigned 13, not 20 because the operator * has higher precedence than +, so it first multiplies 3*2 and then is added to 7.
Here, the operators with the highest precedence appear at the top of the table, those with the lowest appear at the bottom.
Example
#!/usr/bin/python3 a = 20 b = 10 c = 15 d = 5 print ("a:%d b:%d c:%d d:%d" % (a,b,c,d )) e = (a + b) * c / d #( 30 * 15 ) / 5 print ("Value of (a + b) * c / d is ", e) e = ((a + b) * c) / d # (30 * 15 ) / 5 print ("Value of ((a + b) * c) / d is ", e) e = (a + b) * (c / d) # (30) * (15/5) print ("Value of (a + b) * (c / d) is ", e) e = a + (b * c) / d # 20 + (150/5) print ("Value of a + (b * c) / d is ", e)
Output
When you execute the above program, it produces the following result −
a:20 b:10 c:15 d:5 Value of (a + b) * c / d is 90.0 Value of ((a + b) * c) / d is 90.0 Value of (a + b) * (c / d) is 90.0 Value of a + (b * c) / d is 50.0
