如何使用Python漂亮地显示包含词典的列表？

Question

我有一个函数多路径.conf在linux上，嵌入到嵌套字典中的字典如下所示：

[{'blacklist': [{'devnode': '"^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"'}, {'devnode': '"^hd[a-z][[0-9]*]"'}, {'devnode': '"^cciss!c[0-9]d[0-9]*"'}]}, {'defaults': [{'user_friendly_names': 'yes'}]}, {'defaults': [{'udev_dir': '/dev'}, {'polling_interval': '10'}, {'selector': '"round-robin 0"'}, {'path_grouping_policy': 'multibus'}, {'getuid_callout': '"/sbin/scsi_id -g -u -s /block/%n"'}, {'prio_callout': 'none'}, {'path_checker': 'readsector0'}, {'rr_min_io': '100'}, {'max_fds': '8192'}, {'rr_weight': 'priorities'}, {'failback': 'immediate'}, {'no_path_retry': 'fail'}, {'user_friendly_names': 'yes'}]}, {'blacklist': [{'wwid': '26353900f02796769'}, {'devnode': '"^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"'}, {'devnode': '"^hd[a-z]"'}]}, {'devices': [{'device': [{'vendor': '"COMPAQ "'}, {'product': '"HSV110 (C)COMPAQ"'}, {'path_grouping_policy': 'multibus'}, {'getuid_callout': '"/sbin/scsi_id -g -u -s /block/%n"'}, {'path_checker': 'readsector0'}, {'path_selector': '"round-robin 0"'}, {'hardware_handler': '"0"'}, {'failback': '15'}, {'rr_weight': 'priorities'}, {'no_path_retry': 'queue'}]}, {'device': [{'vendor': '"COMPAQ "'}, {'product': '"MSA1000 "'}, {'path_grouping_policy': 'multibus'}]}]}]

我需要用“漂亮的格式”再把它弄出来，看起来像这样：

devices {
   device {
           vendor                  "COMPAQ  "
          product                 "HSV110 (C)COMPAQ"
          path_grouping_policy    multibus
          getuid_callout          "/sbin/scsi_id -g -u -s /block/%n"
          path_checker            readsector0
           path_selector           "round-robin 0"
           hardware_handler        "0"
           failback                15
           rr_weight               priorities
           no_path_retry           queue
  }
   device {
           vendor                  "COMPAQ  "
           product                 "MSA1000         "
           path_grouping_policy    multibus
   }
}
blacklist {
    devnode         "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
    devnode         "^hd[a-z][[0-9]*]"
    devnode         "^cciss!c[0-9]d[0-9]*"
}
and so on the order does not really matter... but the indentations are important to have some 

我用递归函数进行了试验，以“很好地”打印出来，但问题是它的嵌套。。。你知道我怎样才能把这本词典打印出来吗？你知道吗

这是为我做的，虽然它不是通用的，如果有人能帮我把它重写成递归的，那会对我有很大帮助！你知道吗

def pretty(d, indent=0):
for i in d:
    for key, value in i.items():
        print('\t' * indent + str(key) + ' {')
        if isinstance(value, list):
            for item in value:
                if isinstance(item, dict):
                    for key_1, value_1 in item.items():
                        if isinstance(value_1, list):
                            print('\t' * (indent + 2) + str(key_1) + ' {')
                            for x in value_1:
                                for key_2, value_2 in x.items():
                                    print('\t' * (indent + 3) + str(key_2) + 4 * ' ' + str(value_2))
                            print('\t' * (indent + 2) + '}')
                        else:
                            print('\t' * (indent + 1) + str(key_1) + 4 * ' ' + str(value_1))

        print('}')
