In your code you don't define your lists before appending to them, I
guess that will cause an error.
>From the 'file()' entry in the Python manuals :
"""
When opening a file, it's preferable to use open() instead of invoking
this constructor directly. file is more suited to type testing (for
example, writing "isinstance(f, file)").
"""
This might work :
# Set initial conditions
STN_id = list()
STNlat = list()
STNlon = list()
STNelv = list()
LDict = dict(STN_id=STN_id, STNlat=STNlat, STNlon=STNlon, STNelv=STNelv)
# Do the job
for L in open('sitelocations','r') :
LDict[L.split('[')[0]].append(L.split('=')[1].strip('\n'))
