Find a string in python files using Python

Question

I very new to python. I am trying to find all python files that hav the string "DATASOURCE" inside them and to print the path name of the files. I'm using this code:

import os,glob

os.chdir(r"G:\PROJECTS\menofim_3_5\gis")
for file in glob.glob('*.py'):
    with open(file) as f:
        contents = f.read()
    if 'DATASOURCE' in contents:
        print file

I only get this result:

>>> 
findAndReplaceWorkspacePaths-dwg.py
Remove FGB by dataSource excluding specific mxd.py
SelectLayerByLocation2.py
SelectLayerByLocation3.py
>>>

I have succeeded in printing the file name, but I don't know how to print the path name of the files.

Use os.path.join to connect the dirname to the filename:

import os, glob

dirname = r"G:\PROJECTS\menofim_3_5\gis"
os.chdir(dirname)
for filename in glob.glob('*.py'):
    with open(filename) as f:
        contents = f.read()
    if 'DATASOURCE' in contents:
        print os.path.join(dirname, filename)
        print file
