補充:

算餘數:

a = 6%3
print(a)  #0 

b = 8%5
print(b)  #3

一、題目說明

請使用選擇敘述撰寫一程式，讓使用者輸入一個正整數，然後判斷它是3或5的倍數，顯示【x is a multiple of 3.】或【x is a multiple of 5.】；若此數值同時為3與5的倍數，顯示【x is a multiple of 3 and 5.】；如此數值皆不屬於3或5的倍數，顯示【x is not a multiple of 3 or 5.】，將使用者輸入的數值代入x

二、 輸入輸出：

參考解答:

a=eval(input())

if( a % 3 == 0 and a % 5 == 0):
  print(a,"is a multiple of 3 and 5.")
elif(a % 3 == 0 ):
  print(a,"is a multiple of 3.")
elif(a % 5 == 0):
  print(a,"is a multiple of 5.")
else:
  print(a,"is not a multiple of 3 or 5.")

 

看看效果
