问题描述

我在用 Python 自动化无聊的东西的第三章。对于练习guessTheNumber.py,我不清楚“guessesTaken”是如何定义的以及它是如何增加的。

https://automatetheboringstuff.com/chapter3/

这个程序如何: 1. 定义guessesTaken 变量 2. 为每个猜测增加guessesTaken 的值

谢谢,

# This is a guess the number game.
import random
secretNumber = random.randint(1, 20)
print('I am thinking of a number between 1 and 20.')

# Ask the player to guess 6 times.
for guessesTaken in range(1, 7):
    print('Take a guess.')
    guess = int(input())

    if guess < secretNumber:
        print('Your guess is too low.')
    elif guess > secretNumber:
        print('Your guess is too high.')
    else:
        break # this condition is the correct guess!

if guess == secretNumber:
    print('Good job! You guessed my number in ' + str(guessesTaken) +' guesses!')
else:
    print('Nope. The number I was thinking of was ' + str(secretNumber))

解决方案


它被用作循环计数器,它被定义在:

for guessesTaken in range(1, 7):

并且在 for 循环的每次迭代中都会递增。因此,如果循环计数器达到3,则意味着循环运行(没有break)三次,因此用户必须猜测 3 次。
