python.1 변수와 출력 함수

# 값 교환
a, b = 10, 20
print(a, b)  # 10, 20
a, b = b, a
print(a, b)  # 20, 10

# 변수 타입
a = 12345
print(a)        # 12345
print(type(a))  # <class 'int'>
a = 12.123456789123456789
print(a)        # 12.123456789123457
print(type(a))  # <class 'float'>

# 출력방식
print("number")
a, b, c = 1, 2, 3
print(a, b, c)               # 1 2 3
print("number : ", a, b, c)  # number :  1 2 3
print(a, b, c, sep=', ')     # 1, 2, 3
print(a, end=' ')
print(b, end=' ')
print(c, end=' ')
