[Python] 파이썬 날짜시간, 수학, 랜덤함수

 1. 날짜-시간 함수 

import time

t1 = time.time()
print('t1: ', t1)   #유닉스 타입

t2 = time.ctime()
print('t2: ', t2) 

now = time.localtime(time.time())
year = time.strftime('%Y', now)
month = time.strftime('%m', now)
date = time.strftime('%d', now)
hour = time.strftime('%H', now)
min = time.strftime('%M', now)
sec = time.strftime('%S', now)

print('{}년 {}월 {}일 {}:{}:{}'.format(year,month,date,hour,min,sec))

 2. 수학 함수 

import math

r1 = math.ceil(1.2)
r2 = math.ceil(1.8)
r3 = math.floor(1.2)
r4 = math.floor(1.8)
r5 = round(1.2)
r6 = round(1.8)

print('r1: ', r1)
print('r2: ', r2)
print('r3: ', r3)
print('r4: ', r4)
print('r5: ', r5)
print('r6: ', r6)

 3. 랜덤 함수 

import random

num1 = random.random()
print('num1: ', num1)

num2 = num1 * 10
print('num2: ', num2)

num3 = math.ceil(num2)
print('num3: ', num3)
