Question

为什么Python在取消注释时不会像评论的打印行那样，而另一行不存在？

# This is a guess the number game
import random

guessesTaken = 0

myName = input('Hi there! What is your name?')


number = random.randint(1, 20)
print('Well ' + myName + ' I am thinking of a number between 1 and 20')


while guessesTaken < 6:
    guess = int(input('Try and guess what it is!')) # There are 4 spaces in front of print.
    # guess = int(input ())


    guessesTaken = guessesTaken + 1

    if guess < number:
        print('Your guess is too low') # There are 8 spaces in front of print.

    if guess > number:
        print('Your guess is too high')

    if guess == number:
        break   

if guess == number:
    guessesTaken = str(guessesTaken)
   # print('Good Job, ' + myName + '!  You guessed my number ' + number + ' in ' + guessesTaken + ' guesses!')  
    print('Good Job, ' + myName + '!  You guessed my number in ' + guessesTaken + ' guesses!')
if guess != number:
    number = str(number)
    print('I am sorry.  The number I was thinking of was ' + number + ' Thanks for playing, though.')   

input('\n\nPress Enter to exit')

Answer 1

因为number是一个整数。把它变成一个字符串：

print('Good Job, ' + myName + '!  You guessed my number ' + str(number) + ' in ' + guessesTaken + ' guesses!')

但是，使用str.format() string formatting：

要好得多

print('Good Job, {0}!  You guessed my number {1} in {2} guesses!'.format(
    myName, number, guessesTaken))

字符串格式为您转换输入;有关您拥有的格式选项的详细信息，请参阅Format String Syntax documentation。

Answer 2

number是一个整数。您无法添加整数和字符串，因为您收到的错误消息几乎肯定会告诉您。

使用str(number)将其转换为字符串。

Answer 3

问题是number是一个整数。正如您收到的错误消息所述，您无法将整数和字符串一起添加。

您可以使用str(number)将其转换为字符串，就像我在下面所做的那样。

这应该是：

print('Good Job, ' + myName + '!  You guessed my number ' + str(number) + ' in ' + guessesTaken + ' guesses!')

为什么Python不像第31行？
