如何在Python中将用户输入限制为仅某些整数（即：仅在1-100之间，也包括1和100）

Question

我正在尝试为我的计算功课做一个猜数字游戏，但我不知道如何限制用户只输入某些整数（即：1-100，也包括1和100）这是我的代码到目前为止：

import random

BOUNDS = (1, 100)
TRIES_ALLOWED = 6

the_number = random.randint(*BOUNDS)

print("\tWelcome to 'Guess My Number'!\n")
print("I'm thinking of a number between %d and %d." % BOUNDS)
print("Try to guess it in as few attempts as possible.")
print("You only have 6 attempts to guess the number.\n")

for tries in range(TRIES_ALLOWED):
guess = int(input("Take a guess: "))

if guess > 100:
    print ('That is an error please enter a number between 1 and 100')

if guess < 1:
    print ('That is an error please enter a number between 1 and 100')

if guess > the_number:
    print("The number is lower")
elif guess < the_number:
    print("The number is higher")
else:
    print("You guessed it! The number was %d" % (the_number))
    print("And it only took you %d tries!\n\n" % (tries + 1))
    break
else:
print("You failed to guess in time!\n\n")

如果你能帮助我，我们将不胜感激

Answer 1

您可以尝试使用此基本代码来选择1到100之间的数字

import random
num = random.randint(1, 100)
while True:
    print('Guess a number between 1 and 100')
    guess = input()
    i = int(guess)
    if i == num:
        print('You won!!!')
        break
    elif i < num:
               print('Try Higher')
    elif i > num:
               print('Try Lower')
#any recommendations for the game end
print('if you gussed less than 6 times you won')

def prompt_number_range(start, end):
    while True:
        prompt_str = "Please enter a number within the range {0} - {1}:".format(start, end)
        try:
            user_input = raw_input(prompt_str)
        except NameError:
            user_input = input(prompt_str)
        try:
            input_as_int = int(user_input)
            if start <= input_as_int <= end:
                return input_as_int
            else:
                print("that is not within the given boundaries")
        except ValueError:
            pass

print (prompt_number_range(1,100))

以下是上面的代码合并到您的代码中完全正常运行：

import random


def prompt_number_range(start, end):
    while True:
        prompt_str = "Please enter a number within the range {0} - {1}:".format(start, end)
        try:
            user_input = raw_input(prompt_str)
        except NameError:
            user_input = input(prompt_str)
        try:
            input_as_int = int(user_input)
            if start <= input_as_int <= end:
                return input_as_int
            else:
                print("that is not within the given boundaries")
        except ValueError:
            pass

BOUNDS = (1, 100)
TRIES_ALLOWED = 6
the_number = random.randint(*BOUNDS)

print("\tWelcome to 'Guess My Number'!\n")
print("I'm thinking of a number between %d and %d." % BOUNDS)
print("Try to guess it in as few attempts as possible.")
print("You only have 6 attempts to guess the number.\n")
for tries in range(TRIES_ALLOWED):
    user_guess = prompt_number_range(*BOUNDS)
    if user_guess == the_number:
        print("You guessed it! The number was %d" % (the_number))
        print("And it only took you %d tries!\n\n" % (tries + 1))
        break
    elif the_number < user_guess:
        print("The number is lower")
    elif the_number > user_guess:
        print("The number is higher")
else: #for loop finished normally without breaking
    print("You failed to guess in time!\n\n")

尝试使用：

import random

BOUNDS = (1, 100)
TRIES_ALLOWED = 6
win = False
the_number = random.randint(*BOUNDS)

print("\tWelcome to 'Guess My Number'!\n")
print("I'm thinking of a number between %d and %d." % BOUNDS)
print("Try to guess it in as few attempts as possible.")
print("You only have 6 attempts to guess the number.\n")

for tries in range(TRIES_ALLOWED):
    guess = int(input("Take a guess: "))

    if guess > 100:
        print ('That is an error please enter a number between 1 and 100')
        continue

    elif guess < 1:
        print ('That is an error please enter a number between 1 and 100')
        continue

    if guess > the_number:
        print("The number is lower")
    elif guess < the_number:
        print("The number is higher")
    elif guess == the_number:
        win = True
        break

if win == True:
    print("You guessed it! The number was %d" % (the_number))
    print("And it only took you %d tries!\n\n" % (tries + 1))

elif win == False:
    print("You failed to guess in time!\n\n")

这是你要的吗？

function blogRSS(url, container) {
var content = $('.data-content'); //console.log(content);


$.ajax({
  url: document.location.protocol + '//ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=10&callback=?&q=' + encodeURIComponent(url),
  dataType: 'json',
success: function(data) {
  console.log(data.responseData.feed);


  $.each(data.responseData.feed.entries, function(key, value) {
    var thehtml = '<h4><a href="' + value.link + '" target="_blank">' + value.title + '</a></h4>';

    $("body").append(itemLayout);

          $('.panel-heading').last().html(thehtml);
          $('.data-content').last().html(value.content);

          $('.data-title').last().next().slideToggle(0);
      //console.log($('.panel-heading').last().html(value.title));
       //console.log($('.panel-heading').closest('.data-title').text());
       if(localStorage.favorite != null){
           arr = JSON.parse(localStorage.favorite);
           for(var i = 0; i < arr.length; i++){
              // console.log($('.panel-heading').last().text() == arr[i].title);
               if($('.panel-heading').text() == arr[i].title){
                   console.log('match');
                   $('.bkmark_icon').removeClass('glyphicon-star-empty');
                   $('.bkmark_icon').addClass('glyphicon-star');
                   //console.log('match');
               }
           }


       }

  }); $('.data-title').find('h4').addClass('panel-title');

Answer 5

如果此代码的唯一问题是输入验证，则可以替换整个块：

computeTransFun()

有了这个：

void computeTransFun(const char *pat, int M, int TF[][NO_OF_CHARS])

Answer 6

weight = float(input("bag weight "))
while weight<1.01 or weight>3:
        weight=float(input("Give bag weight between 1.01 and 3 :"))
