Python返回不真實的值？

Question

我是Python的新手，我正在Python中進行數字猜測遊戲。然而，當我設置參數：

import random 
numberchosen = random.randint(0,100) 
numberchosenstr = str(numberchosen) 
print ("Let's play a number game") 
numberguessed = input("Guess a number ") 
print ("You guessed " + numberguessed) 

if numberguessed > '100': 
    print ("You guessed too high, choose a number below 100") 

if numberguessed < '0': 
    print ("You guessed too low, choose a number above 0") 

if numberguessed != numberchosen: 
    print ("wrong") 

但是，當我運行的模塊，並選擇比如5號，或任何數字，它是正確的範圍內，但不正確的號碼，它總是返回

Let's play a number game 
Guess a number 5 
You guessed 5 
You guessed too high, choose a number below 100 
wrong 

所以，我的問題是，爲什麼Python返回> 100錯誤，以及有什麼方法可以解決它？

Answer 1

您正在比較字符串，這是按字典順序（即按字母順序，一次一個字符）完成的。但即使有一個int，字符串總是大於數字。你需要採取引號把你的比較數字，並在您input致電int()，就像這樣：

numberguessed = int(input("Guess a number ")) # convert to int 
print ("You guessed {}".format(numberguessed)) # changed this too, since it would error 

if numberguessed > 100: # removed quotes 
    print ("You guessed too high, choose a number below 100") 

if numberguessed < 0: # removed quotes 
    print ("You guessed too low, choose a number above 0")
