[Python] 숫자형

 

정수	123, -345, 0
실수	123.45, -1234.5, 3.4e10
8진수	0o34, 0o25
16진수	0x2A, 0xFF

정수형(integer)

>>> a = 123
>>> a
123
>>> type(a)
int

실수형(floating-point)

>>> a = 6.2
>>> a
6.2
>>> type(a)
float
# 실수형을 다음과 같이 컴퓨터식 지수 표현 방식(scientific notation)으로 표현가능
>>> a = 6.2e-23 # 6.2*10^-23를 의미
>>> a = 6.2E-23 # 위와 같음

복소수(complex)

>>> a = complex(1, 3)
>>> a
(1+3j)
>>> type(a)
complex
>>> a = 3-4j
>>> a
(3-4j)
>>> type(a)
complex
