在python中分割字符串并且使用子列表

Question

我有一根绳子：

"{'osFreeMem': 286494720, 'osUpTime': 19230718, 'sysload': [0.24609375, 0.62109375, 0.734375], 'nodeUpTime': 1831, 'osTotMem': 536870912, 'nodeMemory': {'heapTotal': 8766304, 'heapUsed': 7789588, 'rss': 22773760}}"

我想要一本包含以下值的字典：

^{pr2}$

我怎样才能得到这份名单？在

Answer 1

In [37]: s = "{'osFreeMem': 286494720, 'osUpTime': 19230718, 'sysload': [0.24609375, 0.62109375, 0.734375], 'nodeUpTime': 1831, 'osTotMem': 536870912, 'nodeMemory': {'heapTotal': 8766304, 'heapUsed': 7789588, 'rss': 22773760}}"

In [38]: import ast

In [39]: d = ast.literal_eval(s)

In [40]: d
Out[40]: 
{'nodeMemory': {'heapTotal': 8766304, 'heapUsed': 7789588, 'rss': 22773760},
 'nodeUpTime': 1831,
 'osFreeMem': 286494720,
 'osTotMem': 536870912,
 'osUpTime': 19230718,
 'sysload': [0.24609375, 0.62109375, 0.734375]}

In [41]: d.items()
Out[41]: 
[('osFreeMem', 286494720),
 ('osUpTime', 19230718),
 ('sysload', [0.24609375, 0.62109375, 0.734375]),
 ('nodeUpTime', 1831),
 ('osTotMem', 536870912),
 ('nodeMemory', {'heapTotal': 8766304, 'heapUsed': 7789588, 'rss': 22773760})]

或者

^{pr2}$

Answer 2

您也可以使用内置函数eval

>>>d = eval("{'osFreeMem': 286494720, 'osUpTime': 19230718, 'sysload': [0.24609375, 0.62109375, 0.734375], 'nodeUpTime': 1831, 'osTotMem': 536870912, 'nodeMemory': {'heapTotal': 8766304, 'heapUsed': 7789588, 'rss': 22773760}}")
>>>d
{'osFreeMem': 286494720, 'osUpTime': 19230718, 'sysload': [0.24609375, 0.62109375, 0.734375], nodeUpTime': 1831, 'osTotMem': 536870912, 'nodeMemory': {'heapTotal': 8766304, 'heapUsed': 7789588, 'rss': 22773760}}
