python - 一个简单的python循环问题

Question

这段代码:

import random
print("\tWelcome to the guess my number program\n")

print("im thinking of a number between 1 and 100")
print("try to guess it in 5 attempts\n")

randomNum = random.randint(1,101)

tries = 0

userNumber = int(input("please pick a number"))

while userNumber != randomNum:
    if userNumber > randomNum:
        print ("lower") 
    else:
        print("higher") 
    tries += 1

print ("you guessed it! the number was" , randomNum)

出于某种原因，这会产生无限循环。任何帮助，我还在习惯 python。

Answer 1

您从未在 while 循环内更新您的 userNumber 或 randomNum。所以一旦满足循环条件，就会无限执行。

您需要将 while 循环更新为:

while userNumber != randomNum:
    if userNumber > randomNum:
        print ("lower") 
    else:
        print("higher") 

    tries += 1    
    userNumber = int(input("please pick a number"))
