create a method to looks for some values inside a text

I have this text:

Current Battery Service state:
  AC powered: true
  USB powered: false
  Wireless powered: false
  Max charging current: 1500000
  Max charging voltage: 5000000
  Charge counter: 0
  status: 2
  health: 2
  present: true
  level: 94
  scale: 100
  voltage: 8146
  temperature: 351
  technology: Li-ion

and want to create a method to get the value maybe for level or voltage, something like this get_battery_status(property) and pass it “level” and it should return 94 in this case, or pass “temperature” and return 351 on python 3

Answer

You can build a dictionary from the text file, something like:

d ={}
with open("text.txt") as f:
  for l in list(f)[1:]:
    key, value = l.split(":")
    d[key.strip()] = value.strip()
print(d)

def get_battery_status(k):
  return d[k]
    
print(get_battery_status('level'))
print(get_battery_status('Max charging voltage'))

Output:

{'AC powered': 'true', 'USB powered': 'false', 'Wireless powered': 'false', 'Max charging current': '1500000', 'Max charging voltage': '5000000', 'Charge counter': '0', 'status': '2', 'health': '2', 'present': 'true', 'level': '94', 'scale': '100', 'voltage': '8146', 'temperature': '351', 'technology': 'Li-ion'}
94
5000000

Update:

but I have the whole text inside a variable like this…

Based on your comment, you can use:

text = """Current Battery Service state:
  AC powered: true
  USB powered: false
  Wireless powered: false
  Max charging current: 1500000
  Max charging voltage: 5000000
  Charge counter: 0
  status: 2
  health: 2
  present: true
  level: 94
  scale: 100
  voltage: 8146
  temperature: 351
  technology: Li-ion"""

d = {}
for l in [l.strip() for l in text.split("n")[1:]]:
  key, value = l.split(":")
  d[key.strip()] = value.strip()
print(d)
  
def get_battery_status(k):
  return d[k]

print(get_battery_status('level'))
print(get_battery_status('Max charging voltage'))
