使用python编写七段数码管两位数倒计时

这是一个简单的Python代码，可以倒计时两位数的数码管。

import time

# 数码管字典，用于对应每个数字和对应管的位置
digit_segments = {
    0: ('###', '# #', '# #', '# #', '###'),
    1: ('  #', '  #', '  #', '  #', '  #'),
    2: ('###', '  #', '###', '#  ', '###'),
    3: ('###', '  #', '###', '  #', '###'),
    4: ('# #', '# #', '###', '  #', '  #'),
    5: ('###', '#  ', '###', '  #', '###'),
    6: ('###', '#  ', '###', '# #', '###'),
    7: ('###', '  #', '  #', '  #', '  #'),
    8: ('###', '# #', '###', '# #', '###'),
    9: ('###', '# #', '###', '  #', '###'),
}

# 倒计时函数，接收两个参数，分钟和秒钟，打印出对应的倒计时
def countdown(minutes, seconds):
    # 转换为秒钟
    total_seconds = minutes * 60 + seconds
    while total_seconds:
        # 分钟和秒钟
        minutes, seconds = divmod(total_seconds, 60)
        # 数码管列表，用于保存每个数码管的字典
        digit_list = []
        # 将分钟和秒钟转换为两位整数，并将每个整数添加到数码管列表中
        for number in f'{minutes:02d}{seconds:02d}':
            digit = {}
            for i, row in enumerate(digit_segments[int(number)]):
                digit[i] = row
            digit_list.append(digit)
        # 输出倒计时
        print(' '.join(''.join(digit[i][j] for digit in digit_list) for j in range(5)))
        # 延迟一秒钟
        time.sleep(1)
        # 减少一秒钟
        total_seconds -= 1

# 倒计时2分30秒
countdown(2, 30)

输出：
