Hello everyone,
I have written this small utility function for transforming legacy
file to Python dict:
def lookupdmo(domain):
lines = open('/etc/virtual/domainowners','r').readlines()
lines = [ [y.lstrip().rstrip() for y in x.split(':')] for x in
lines]
lines = [ x for x in lines if len(x) == 2 ]
d = dict()
for line in lines:
d[line[0]]=line[1]
return d[domain]
The /etc/virtual/domainowners file contains double-colon separated
entries:
domain1.tld: owner1
domain2.tld: own2
domain3.another: somebody
...
Now, the above lookupdmo function works. However, it's rather tedious
to transform files into dicts this way and I have quite a lot of such
files to transform (like custom 'passwd' files for virtual email
accounts etc).
Is there any more clever / more pythonic way of parsing files like
this? Say, I would like to transform a file containing entries like
the following into a list of lists with doublecolon treated as
separators, i.e. this:
tm:$1$aaaa$bbbb:1010:6::/home/owner1/imap/domain1.tld/tm:/sbin/nologin
would get transformed into this:
[ ['tm', '$1$aaaa$bbbb', '1010', '6', , '/home/owner1/imap/domain1.tld/
tm', '/sbin/nologin'] [...] [...] ]
