FINAL SOLUTION:
### LOOP OVER DIRECTORY
location = '/Users/spyros/Desktop/3NY8MODELSHUMAN/HomologyModels'
zdata = []
for filename in os.listdir(location):
filename = os.path.join(location, filename)
try:
zdata.extend(extract_zcoord(filename))
except NameError:
print "No such file!"
except SyntaxError:
print "Check Your Syntax!"
except IOError:
print "PDB file NOT FOUND!"
else:
continue
print 'Z-VALUES FOR ALL CHARGED RESIDUES'
print zdata #diagnostic
### WRITE Z-COORDINATE LIST TO A BINARY FILE
import pickle
f1 = open("z_coords1.dat", "wb")
pickle.dump(zdata, f1)
f1.close()
f2 = open("z_coords1.dat", "rb")
zdata1 = pickle.load(f2)
f2.close()
assert zdata == zdata1, "error in pickle/unpickle round trip!"

I only had the filename and not its path, that's why the system was not
able to locate the file, so
filename = os.path.join(location, filename) was used to solve that.
Many thanks to everyone for their time and efforts!
