在python中如何将字符串转换为字典以检索特定值

Question

One function returns below String s : s = 'Power On Enabled: On\\nsignalStrength: -050\\nip address: 192.168.75.123\\n'

I want to read the value of ip address in above string s. Used below code : /* Code */

s = 'Power On Enabled: On\nsignalStrength: -050\nip address: 
192.168.75.123\n' 

ipdict = {}
newstr = s.replace("\n",",")
newdict = ipdict.update(newstr)
ip = newdict.get('ip address')
print ip

Got below Error : "dictionary update sequence element #0 has length 1; 2 is required"

Answer 1

s = 'Power On Enabled: On\nsignalStrength: -050\nip address: 192.168.75.123\n'
s = s.strip().split("\n")
d = {}
for i in s:
    key, val = i.split(":")
    d[key] = val.strip()

print d
print d["ip address"]

Output:

{'signalStrength': '-050', 'Power On Enabled': 'On', 'ip address': '192.168.75.123'}

 192.168.75.123
