在python 3.2中，如何比较符号，例如>

Question

我正在编写一个函数，它将猜测我在想什么数字，但是如何比较>或小于符号等符号呢？

def NumberGuess (low,high):
    guess = ((low+high//2)

    if str(input(guess,"?")) == (">") :
         NumberGuess (guess,high)
    elif str(input(guess,"?")) == "<":
         NumberGuess (low,guess)
    else:
         str(input(guess,"?")) == "="

到目前为止，这是我所拥有的，我可以用另一种方式来做，但这现在困扰着我，我想弄清楚所有帮助都值得感谢！

def NumberGuess (lo,hi):
    guess = (lo+hi)//2
    user_guess = input("Please, input '>' or '<' as a guess: ")
    if user_guess == ">" :
        ReverseNumberGuess (guess,hi)
    elif user_guess == "<":
        ReverseNumberGuess (lo,guess)
