You can source the file in python provided that you make it python
friendly:-
STN_id[1]='AAA' instead of STN_id[1]=AAA
...
-----------
import re
# Read the file
fd = open('sitelocations')
lines = fd.readlines()
fd.close()
# Make it python friendly: put all values in 'single quotes'
cmd = '\n'.join([re.sub( r'^([^=]+)=(.*)$', r"\1='\2'", v) for v in lines])
# Create variables as list of appropriate size with default values (assuming
0)
max = 5
STN_id, STNlat, STNlon, STNelv = [0]*max, [0]*max, [0]*max, [0]*max
# Execute the command and all your variables are populated ...
exec(cmd)
-------------------
Not sure if this is a better way :) But atleast it will make the file
sitelocations order invariant - implies you can interchange the lines
without breaking the logic.
Caveat - list in python starts at 0 index so STN_id[1] is not the first
element but the second element. But you can filter unwanted items from the
list if you want as in -
[ x for x in STN_id if x != 0 ]
