创建一个简单的倒数计时器Python

Question

Could someone give me a tip? I am attempting to create a countdown timer that will reset based on the episodes...

For example I was hoping this code below would countdown from 10 - 0, 15 times ( total_episodes ) but it only counts down once... Any tips greatly appreciated..

import time

total_episodes = 15 
n=10

for episode in range(total_episodes):

    for i in range(n):
        time.sleep(1)
        n -= 1
        print("countdown episode timer",n)

I need the time.sleep as my real scenario I am trying to create something that will countdown 10 minutes for 15 times/episodes..

You're forgetting to reset your n .

for episode in range(total_episodes):

    n = 10   #  do this

    for i in range(n):
        time.sleep(1)
        n -= 1
        print("countdown episode timer", n)

Without resetting your n , the nested for -loop will evaluate i in range(0) which is just an empty range.

OR you could even do without the n .

for episode in range(total_episodes):

    for i in range(10, 0, -1):
        time.sleep(1)
        print("countdown episode timer", i)
