python判断一个数是奇数还是偶数_在python中检查一个数字是奇数还是偶数

参见英文答案 > python – checking odd/even numbers and changing outputs on number size                                    15个

我正在尝试制作一个程序,检查一个单词是否是一个回文并且我已经到目前为止它可以使用具有偶数数字的单词.我知道如果字母数量是奇数,如何使它做某事但我只是不知道如何找出一个数字是奇数.有没有简单的方法来查找数字是奇数还是偶数？

仅供参考,这是我的代码：

a = 0

while a == 0:

print("\n \n" * 100)

print("Please enter a word to check if it is a palindrome: ")

word = input("?: ")

wordLength = int(len(word))

finalWordLength = int(wordLength / 2)

firstHalf = word[:finalWordLength]

secondHalf = word[finalWordLength + 1:]

secondHalf = secondHalf[::-1]

print(firstHalf)

print(secondHalf)

if firstHalf == secondHalf:

print("This is a palindrom")

else:

print("This is not a palindrom")

print("Press enter to restart")

input()

谢谢

解决方法:

if num % 2 == 0:

pass # Even

else:

pass # Odd

％符号就像除了它只检查余数一样,所以如果除以2的数字的余数为0,那么它甚至是奇数.
