Python：遍历列表，将空白输出到第二个列表，然后按顺序调用

Question

感谢您抽出宝贵时间帮助我。 谈到Python时仍然是一个菜鸟，但我慢慢地到了那里。

背景故事：基本上我将配置从PBX转移到CSV文件然后迁移到另一个系统。

我被困的地方：目前我有一个扩展号码列表，然后是语音邮件配置。 并非每部手机都有语音邮件电子邮件地址，因此目前我正在做的是比较数据以查看当前分机是否有关联的电子邮件。 由于数据的导出方式，我将所有内容存储到列表中，所有这些都需要排队。

我需要它做什么：我需要将电子邮件很好地输出到列表中并使其与扩展列表对齐。 例如：

list_extension_email = [''，'test @ test'，''，''，'test2 @ test']

list_extension_numbers = ['1000'，'401'，'402'，'403'，'404']

码：

list_extension_voicemail = ['401, test@test', '404, test2@test']
list_extension_numbers = ['1000', '401', '402', '403', '404']
list_extension_email = []
line_variable = 0
blank_voicemails = 0

for extension in list_extension_numbers:
    extension_number = list_extension_numbers[line_variable]
    blank_line = " "
    for extension_voicemail in list_extension_voicemail:
      extension_and_voicemail = extension_voicemail.split(',')
      if extension_and_voicemail[0] in extension_number:
        while blank_voicemails != 0:
          list_extension_email.append(blank_line)
          blank_voicemails-=1
        list_extension_email.append(extension_and_voicemail[1])
        blank_voicemails = 0
      else:
        blank_voicemails+=1


extension_email = list_extension_email[line_variable]

对不起，如果这是非常模糊和非描述性的，我愿意听取任何解决方案。 再一次，谢谢大家

我认为这样做你想要的：

list_extension_voicemail = ['401, test@test', '404, test2@test']
list_extension_numbers = ['1000', '401', '402', '403', '404']

# Make list of empty emails
list_extension_email = [''] * len(list_extension_numbers)
# Make a dict that gives you the list index for each number
number_idx = {number: idx for idx, number in enumerate(list_extension_numbers)}
for number_email in list_extension_voicemail:
    # Split by comma
    number, email = number_email.split(',')
    # Remove extra spaces
    number = number.strip()
    email = email.strip()
    # Set email in list if number exists
    if number in number_idx:
        list_extension_email[number_idx[number]] = email

# Print result
print('list_extension_email =', list_extension_email)
print('list_extension_numbers =', list_extension_numbers)

输出：

list_extension_email = ['', 'test@test', '', '', 'test2@test']
list_extension_numbers = ['1000', '401', '402', '403', '404']
