Python command line output

I have a data file. A file is the result generated from a shell script file:

|a |869 | |b |835 | |c |0 | |d |0 | |e |34 | |f |3337

How can I get a = 869 from this?

You can do it:

 output = {} for line in open("myfile"): parts = line.split('|') output[parts[1].strip()] = parts[2].strip() print output['a'] // prints 869 print output['f'] // prints 3337

Or, using the csv module, as suggested by Evgeny Morozov:

 import csv output = {} reader = csv.reader(open("C:/output.txt"), delimiter='|') for line in reader: output[line[1].strip()] = line[2].strip() print output['a'] // prints 869 print output['f'] // prints 3337

 lines = file("test.txt").readlines() d = dict([[i.strip() for i in l.split("|")[1:3]] for l in lines if l.strip()])

For instance:

 >>> lines = file("test.txt").readlines() >>> d = dict([[i.strip() for i in l.split("|")[1:3]] for l in lines if l.strip()]) >>> d['a'] '869'

You can also use csv module with delimiter | .

Maybe not the most Pythonic way, but this should work if your shell output is stored in the f.txt file and you are looking for each line to be processed:

 h = open("f.txt", "rt") inp = h.readline() while inp: flds = inp.split('|') str = flds[1].strip() + " = " + flds[2].strip() print str inp = h.readline()
