使用While循环的猜数字游戏 - Python

Question

我正在尝试制作一个“猜数字（1到10之间）”的游戏，但我的循环似乎一直在运行。我想让程序让用户猜一个数字，然后显示这个数字是太高还是太低，然后自动重新开始（循环），让用户可以再次选择。但是这段代码让它一直运行下去。你们能帮我吗？

import random

def numberGuess():
  printNow("I'm thinking of a number between 1 and 10")
  guess = 0 # give guess a starting value
  randNum = random.randrange(1,11) # this line generates a random number
  guess = int(input("Try to guess the number:")) # ask user for a number
  print randNum 
  while guess != randNum:
    if (guess == randNum): 
      print "You got it!"
    if (guess > randNum):
      print "Wrong! You guessed too high"
    if (guess < randNum):
      print "Wrong! You guessed too low"

Answer 1

在编程中，有时候我们需要让程序在特定的条件下执行某些操作。这就像给程序设定了一些规则，只有当这些规则被满足时，程序才会继续进行。

比如说，你可能想要在用户输入的数字大于10时，程序才显示一条消息。这种情况下，你就需要用到“条件语句”。条件语句就像是一个检查点，程序会在这里停下来，看看条件是否成立。如果成立，程序就会执行你设定的操作；如果不成立，程序就会跳过这些操作，继续往下走。

简单来说，条件语句帮助程序根据不同的情况做出不同的反应，就像是生活中的选择一样。

import random

def numberGuess():
  randNum = random.randrange(1,11) # this line generates a random number
  guess = int(input("Try to guess the number:")) # ask user for a number
  print (randNum)
  while True:
    if (guess == randNum):
        print ("You got it!")
        break
    if (guess > randNum):
        print ("Wrong! You guessed too high")
        guess = int(input("Try to guess the number:"))  # ask user for a number
    if (guess < randNum):
        print ("Wrong! You guessed too low")
        guess = int(input("Try to guess the number:"))  # ask user for a number

numberGuess()

Answer 2

使用这个：

import random

def numberGuess():
  print("I'm thinking of a number between 1 and 10")
  randNum = random.randrange(1,11) # this line generates a random number
  while guess != randNum:
    guess = int(input("Try to guess the number:")) # ask user for a number
    if (guess == randNum): 
      print "You got it!"
    if (guess > randNum):
      print "Wrong! You guessed too high"
    if (guess < randNum):
      print "Wrong! You guessed too low"

numberGuess()

Answer 3

如果你把 input 这个语句放到 while 循环里面，就没问题了。

Answer 4

你忘了在循环里面进行猜测了

  while guess != randNum:
    guess = int(input("Try to guess the number:"))
    if (guess > randNum):
      print "Wrong! You guessed too high"
    if (guess < randNum):
      print "Wrong! You guessed too low"
  print "You got it!"
