我希望在输出中显示弹珠点，并且随着弹珠数量的减少，星号也会减少。我不知道什么命令会让星号在 while 循环运行时下降。

#!/usr/bin/env python3

marbles = 10  #You start out with 10 marbles
marble_dots = "**********" #Pretend these are ten marbles

while (marbles > 0):
   print(marble_dots[:10])

   #This prints out how many marbles you have left.
   # We have to say str(marbles) because marbles is a number
   # and we want to use it in a string (letters and other characters)
   print("You have " + str(marbles) + " marbles left.")

   if (marbles < 4):
       print("Warning: You are running low on marbles!!")

   #This is another way of saying "Subtract 1 from the marbles variable"
   # It is logically the same as writing "marbles = marbles - 1", just shorter
   marbles -= 1

   # Make a newline, so there's an empty line before the next time we run this loop
   print("")

快到了!

只需将打印内容从硬编码的 10 更改为剩余弹珠的数量

while (marbles > 0):
   
   print(marble_dots[:marbles])

您也可以将其替换为:

print('*' * marbles)

每个弹珠都会打印一次 *。
