【问题描述】:
以下程序在字符串中使用 {0},我不确定它是如何工作的,它出现在有关 Python 迭代的在线教程中,我似乎找不到任何解释它的地方。
import random
number = random.randint(1, 1000)
guesses = 0
print("I'm thinking of a number between 1 and 1000.")
while True:
guess = int(input("\nWhat do you think it is? "))
guesses += 1
if guess > number:
print("{0} is too high.".format(guess))
elif guess < number:
print("{0} is too low.".format(guess))
else:
break
print("\nCongratulations, you got it in {0} guesses!\n".format(guesses))
谢谢!
