Answer 1

This would work for this given file:

blah bloo cake
donky cat sparrow
nago cheese

The code:

lcount = 1
with open("file", "r") as f:
    for line in f:
        if word in line:
            testline = line.split()
            ind = testline.index("sparrow")
            print "Word sparrow found at line %d, word %d" % (lcount, ind+1)
            break
        else:
            lcount += 1

Would print:

Word sparrow found at line 2, word 3

You should be able to modify this quite easily to make a function or different output I hope.

Although I’m still really not sure if this is what you’re after…

Minor edit:
As a function:

def findword(objf, word):
    lcount = 1
    found = False
    with open(objf, "r") as f:
        for line in f:
            if word in line: # If word is in line
                testline = line.split()
                ind = testline.index(word) # This is the index, starting from 0
                found = True
                break
            else:
                lcount += 1
        if found:
            print "Word %s found at line %d, word %d" % (word, lcount, ind+1)
        else:
            print "Not found"

Use:

>>> findword('file', "sparrow")
Word sparrow found at line 2, word 3
>>> findword('file', "donkey")
Not found
>>> 

Shrug Not the best method I’ll give it that, but then again it works.
