I have 15 values that I want to get from a config file and store them in separate variables.
I am using
from ConfigParser import SafeConfigParser
parser = SafeConfigParser()
parser.read(configFile)
and it is a really good library.
Option #1
If I change the name of the variable and want it to match the config file entry I have to edit the corresponding line in the function
Python: |
def fromConfig():
#open file
localOne = parser.get(section, 'one')
localTwo = parser.get(section, 'two')
return one, two
one = ''
two = ''
#etc
one, two = fromConfig()
|
Option #2
It is cleaner to see where the variables get their values from, but then I would be opening and closing the file for every variable
Python: |
def getValueFromConfigFile(option):
#open file
value = parser.get(section, option)
return value
one = getValueFromConfigFile("one")
two = getValueFromConfigFile("two")
|
Option #3
This one doesn't make much sense since I have to have another list of all my variable names, but the function is cleaner.
Python: |
def getValuesFromConfigFile(options):
#open file
values = []
for option in options:
values.append(parser.get(section, option))
return values
one = ''
two = ''
configList = ["one", "two"]
one, two = getValuesFromConfigFile(configList)
