Python 3-算術演算子の例

変数 a が値10を保持し、変数 b が値20を保持すると仮定します-

Operator	Description	Example
PLUS Addition	Adds values on either side of the operator.	a PLUS b = 31
- Subtraction	Subtracts right hand operand from left hand operand.	a – b = -11
*Multiplication	Multiplies values on either side of the operator	a* b = 210
/Division	Divides left hand operand by right hand operand	b/a = 2.1
% Modulus	Divides left hand operand by right hand operand and returns remainder	b % a = 1
** Exponent	Performs exponential (power) calculation on operators	a**b =10 to the power 20
//	Floor Division - The division of operands where the result is the quotient in which the digits after the decimal point are removed. But if one of the operands is negative, the result is floored, i.e., rounded away from zero (towards negative infinity):	9//2 = 4 and 9.0//2.0 = 4.0, -11//3 = -4, -11.0//3 = -4.0

例

変数 a が値10を保持し、変数 b が値20を保持すると仮定します-

#!/usr/bin/python3

a = 21
b = 10
c = 0

c = a + b
print ("Line 1 - Value of c is ", c)

c = a - b
print ("Line 2 - Value of c is ", c )

c = a * b
print ("Line 3 - Value of c is ", c)

c = a/b
print ("Line 4 - Value of c is ", c )

c = a % b
print ("Line 5 - Value of c is ", c)

a = 2
b = 3
c = a**b
print ("Line 6 - Value of c is ", c)

a = 10
b = 5
c = a//b
print ("Line 7 - Value of c is ", c)

出力

上記のプログラムを実行すると、次の結果が生成されます-

Line 1 - Value of c is  31
Line 2 - Value of c is  11
Line 3 - Value of c is  210
Line 4 - Value of c is  2
Line 5 - Value of c is  1
Line 6 - Value of c is  8
Line 7 - Value of c is  2
