Hello everyone,
Here's my solution for reading binary data (unformatted mixed types) and
packing it into a dictionary. It works, but somehow doesn't seem so
'pythonic'. Just seeking comments on how I might make it more efficient.
Thanks!
def readheader(filename):
import struct
I={0:'rl',1:'ibdate',2:'ibtime',3:'version',4:'void1',5:'void2',6:'loutstep',7:'loutaver',8:'loutsample',9:'void3',10:'void4',11:'outlon0',12:'oulat0',13:'numxgrid',14:'numygrid',15:'dxout',16:'dyout',17:'void5',18:'void6',19:'numzgrid'}
B={}
f2=file(filename,'rb')
#Define Header format
Dfmt=['i','i','i','13s','i','i','i','i','i','i','i','f','f','i','i','f','f','i','i','i']
#format for binary reading first bits
if f2:
print filename + ' has been opened'
#create a dictionary from header file
a=[struct.unpack(ft,f2.read(struct.calcsize(ft))) for ft in Dfmt]
for i in range(len(a)):
B[I[i]]=a[i][0]
