Question

以下脚本询问用户信息，将信息存储为变量，然后创建一个文件，将变量插入文本中的各个位置。创建的文件是一个html网页，然后可以在我的Web服务器上运行。该示例显示了4组变量并且运行良好。但是，我想询问用户所需的总数，然后执行一个循环，不断询问相同的信息（即视频编号，描述，文件夹名称），直到达到总数。对于每次迭代，我想生成html文本的选择部分。我是一个Python noob所以非常感谢任何帮助/反馈。提前谢谢！

# The next 12 variables prompt the use for the label, description and folder names for 4 videos
Video1_Num = raw_input('Enter the number label for Video 1: ')
Video1_Desc = raw_input('Enter the description of Video 1: ')
Video1_Fold = raw_input('Enter the name of the folder where video 1 is stored: ')

Video2_Num = raw_input('Enter the number label for Video 2: ')
Video2_Desc = raw_input('Enter the description of Video 2: ')
Video2_Fold = raw_input('Enter the name of the folder where video 2 is stored: ')

Video3_Num = raw_input('Enter the number label for Video 3: ')
Video3_Desc = raw_input('Enter the description of Video 3: ')
Video3_Fold = raw_input('Enter the name of the folder where video 3 is stored: ')

Video4_Num = raw_input('Enter the number label for Video 4: ')
Video4_Desc = raw_input('Enter the description of Video 4: ')
Video4_Fold = raw_input('Enter the name of the folder where video 4 is stored: ')

Answer 1

您可以使用dict列表。 video_list = [] 假设你得到三个值，num_val，desc_str和fold_num作为输入然后制作一个视频词典为video={'num': num_val,'desc':'desc_str','fold_num':fold_num} 现在，您可以继续按照下面的说明在video_list中推送它，并可以访问它们，如下所述。 Imp注意：在输入数据时，可能需要按照int或string等数据类型进行转换。

video_list =[]
Video_count =4
for n in range(Video_count):
    num_val= input('enter number...')
    desc_str= input('enter desc...')
    fold_num= input('enter fold...')
    video={'num': num_val,'desc':'desc_str','fold_num':fold_num}
    video_list.append(video)

您可以按索引和元素访问元素，如下所示：

    video_list[index]['num_val']

其中index是介于0和len之间的任何数字（video_list）-1（包括两者）。 num_val是dict的元素，它可以是num_val，desc_str和fold_num中的任何一个。
