Hi all,
I've written a function that reads a specifically formatted text file
and spits out a dictionary. Here's an example:
config.txt:
Destination = C:/Destination
Overwrite = True
Here's my function that takes 1 argument (text file)
the_file = open(textfile,'r')
linelist = the_file.read().split('\n')
You could use .splitlines() or iterate over the file itself.
the_file.close()
configs = {}
for line in linelist:
try:
key,value = line.split('=')
key.strip()
value.strip()
key.lower()
value.lower()
Strings are immutable. These methods don't modify the strings, but
_return_ the result.
configs[key] = value
except ValueError:
break
'break' will leave the loop. Is this intentional?
so I call this on my config file, and then I can refer back to any
config in my script like this:
shutil.move(your_file,configs['destination'])
which I like because it's very clear and readable.
So this works great for simple text config files. Here's how I want
to improve it:
I want to be able to look at the value and determine what type it
SHOULD be. Right now, configs['overwrite'] = 'true' (a string) when
it might be more useful as a boolean. Is there a quick way to do
this? I'd also like to able to read '1' as an in, '1.0' as a float,
etc...
I remember once I saw a script that took a string and tried int(),
float() wrapped in a try except, but I was wondering if there was a
more direct way.
The way you saw was the safe, and recommended, way.
When checking for Boolean you might want to ignore the case; something
like:
bool_dict = {"false": False, "true": True}
...
try:
value = bool_dict[value.strip().lower()]
except ValueError:
# Not a Boolean.
...
