为什么 Python 在未注释且另一行不存在时不喜欢已注释的打印行？

# 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')

因为number是整数。也把它变成一个字符串：

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

str.format()但是，使用字符串格式会更好：

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

字符串格式化为您转换输入；有关您拥有的格式选项的更多详细信息，请参阅格式字符串语法文档。

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

使用 . 将其转换为字符串str(number)。

问题是它number是一个整数。正如您收到的错误消息所述，您不能将整数和字符串相加。

str(number)您可以像我在下面所做的那样将其转换为字符串。

这应该是：

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