how to load data and store the data from a file using numpy

Question

I have the following file like this:

2 qid:1 1:0.32 2:0.50 3:0.78 4:0.02 10:0.90
5 qid:2 2:0.22 5:0.34 6:0.87 10:0.56 12:0.32 19:0.24 20:0.55
...

he structure is follwoing like that:

output={} rel=2 qid=1 features={} # the feature list "1:0.32 2:0.50 3:0.78 4:0.02 10:0.90" output.append([rel,qid,features]) ... How can I write my python code to load the data, thanks

Answer 1

For reading use something like this (data is in file 'fname'):

f = open(fname)
lines = f.readlines(f)
for line in lines:
    elements = line.split(' ')
    rel = int(elements[0])
    qid = int(elements[1].split(':')[1])
    featurelist = elements[2:]
    # get the various features again with splitting at ':'
    # you get the idea ...
