산술 연산자(뺄셈)

 

 

 

뺄셈 연산자

 

 

 

 

 

 

num1 = 12
num2 = 23

fNum1 = 1.23
fNum2 = 0.12

str1 = 'Kim'
str2 = ' '
str3 = 'jieun'

 

 

 

* 뺄셈 연산자

    • 정수를 이용한 뺄셈

result = num1 - num2
print(f'num1 : {num1}')
print(f'num2 : {num2}')
print(f'result : {result}')

num1 : 12
num2 : 23
result : -11

 

 

    • 실수를 이용한 뺄셈

result = fNum1 - fNum2
print(f'fNum1 : {fNum1}')
print(f'fNum2 : {fNum2}')
print(f'result : {result}')
print(f'type of result : {type(result)}')

fNum1 : 1.23
fNum2 : 0.12
result : 1.1099999999999999
type of result : <class 'float'>

 

 

 

    • 정수와 실수를 이용한 뺄셈

result = num1 - fNum2
print(f'num1 : {num1}')
print(f'fNum1 : {fNum1}')
print(f'result : {result}')
print(f'type of result : {type(result)}')

num1 : 12
fNum1 : 1.23
result : 11.88
type of result : <class 'float'>

 

 

    • 문자(열)을 이용한 뺄셈

불가능하다.

result = str1 - str2 - str3
TypeError : unsupported operand type(s) for -: 'str' and 'str'
