Python - combination

def combination(m,n):
    if n==0 or m==n:
        return 1
    else:
        return combination(m-1,n)+combination(m-1,n-1)
    
    
m = int(input('please fill m value :'))
n = int(input('please fill n value :'))
ans = combination(m,n)
print(ans)

Python - summation

def summation(num):
    if num == 1:
        return 1
    else:
        return num + summation(num-1)

n = int(input('please fill in an integer number :'))
ans = summation(n)
print('the result is :', ans)

Python - adding label

def label(sentence):
    y = str('
') + sentence + str('
')
    print(y)

s = str(input('please paste code :'))
ans = label(s)

Python - 查日期

from datetime import datetime
#import datetime
def ymd():
    now = datetime.now()
    return (now.year, now.month, now.day)
y, m, d = ymd()
print(y,m,d)

Python - 質數檢查

import math
def prime(num):
    j = 2
    while j<=math.sqrt(num):
        if(num % j == 0):
            return False
        j += 1
    return True
for i in range(2,101):
    if prime(i):
        print(i,'is prime number')
