问题描述
我从子流程命令获取数据作为字符串.我想将此数据存储在字典中.我怎样才能最好地做到这一点?
I getting data from subprocess command as a string. I want to store this data in a dict. How best do I achieve this?
这是数据示例:(我已经从子流程中将其作为字符串返回了.)
Here is data example: (I have returned this as a string from subprocess.)
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
loop0 7:0 0 140.7M 1 loop /snap/gnome-3-26-1604/82
loop1 7:1 0 89.3M 1 loop /snap/core/6673
sda 8:0 0 11G 0 disk
├─sda1 8:1 0 10.9G 0 part /
├─sda14 8:14 0 4M 0 part
└─sda15 8:15 0 106M 0 part /boot/efi
这是我想要的输出:
{block device 1:
{ "name" : value,
"maj:min" : value,
"RM" : value,
"SIZE" : value,
"RO": value,
"TYPE": value,
"MOUNTPOINT" : value},
block device 2:
{ "name" : value,
"maj:min" : value,
"RM" : value,
"SIZE" : value,
"RO": value,
"TYPE": value,
"MOUNTPOINT" : value},
...
}
这是我尝试实现的对这些数据进行排序的方法
Here is the method I am trying to implement to sort this data
def multiple_column_dict(a_string):
a_dict = {}
lines = re.split("\n", a_string)
for l in lines:
l = re.split(" +", l)
a_dict = dict(zip(l[::2], l[1::2]))
return a_dict
注1:我知道zip方法不正确
Note 1:I know that the zip method is incorrect
注2:我不知道该如何计算-例如当'\ n'出现在'disk'之后.
Note 2:I don't know how to account for items that are - e.g. when '\n' comes in after 'disk'.
推荐答案
使用itertools.zip_longest
->如果使用python2 izip_longest
Using itertools.zip_longest
--> If using python2 izip_longest
例如:
from itertools import zip_longest
data = """NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
loop0 7:0 0 140.7M 1 loop /snap/gnome-3-26-1604/82
loop1 7:1 0 89.3M 1 loop /snap/core/6673
sda 8:0 0 11G 0 disk
├─sda1 8:1 0 10.9G 0 part /
├─sda14 8:14 0 4M 0 part
└─sda15 8:15 0 106M 0 part /boot/efi"""
result = []
header = None
for line in data.splitlines():
line = line.strip().split()
if not header:
header = line
else:
result.append(dict(zip_longest(header, line, fillvalue="")))
输出:
{'NAME': 'loop0', 'MAJ:MIN': '7:0', 'RM': '0', 'SIZE': '140.7M', 'RO': '1', 'TYPE': 'loop', 'MOUNTPOINT': '/snap/gnome-3-26-1604/82'}
{'NAME': 'loop1', 'MAJ:MIN': '7:1', 'RM': '0', 'SIZE': '89.3M', 'RO': '1', 'TYPE': 'loop', 'MOUNTPOINT': '/snap/core/6673'}
{'NAME': 'sda', 'MAJ:MIN': '8:0', 'RM': '0', 'SIZE': '11G', 'RO': '0', 'TYPE': 'disk', 'MOUNTPOINT': ''}
{'NAME': '├─sda1', 'MAJ:MIN': '8:1', 'RM': '0', 'SIZE': '10.9G', 'RO': '0', 'TYPE': 'part', 'MOUNTPOINT': '/'}
{'NAME': '├─sda14', 'MAJ:MIN': '8:14', 'RM': '0', 'SIZE': '4M', 'RO': '0', 'TYPE': 'part', 'MOUNTPOINT': ''}
{'NAME': '└─sda15', 'MAJ:MIN': '8:15', 'RM': '0', 'SIZE': '106M', 'RO': '0', 'TYPE': 'part', 'MOUNTPOINT': '/boot/efi'}

c = 1
for line in data.splitlines():
