python - 在输出中添加星号

Question

我最近开始学习Python，我有一个倒计时器。它工作正常，但我想在输出中添加一个星号。

输出的重新定义是:

Countdown timer: How many seconds? 4          
4****   
3***   
2**   
1*  
Blast off

到目前为止我已经:

import time

countDown = input('Countdown Timer: How many seconds?')

for i in range (int(countDown), 0, -1):
    print (i)
    time.sleep(1)
print ('BLAST OFF')

Answer 1

只需在打印数字时添加 * 即可。

import time

countDown = input('Countdown Timer: How many seconds?')

for i in range (int(countDown), 0, -1):
    print (i,"*"*(i))
    time.sleep(1)
print ('BLAST OFF')

或 print str(i)+"*"*(i) - 数字后不留空格。
