My guess is that you have a line, perhaps the last one in the file,
which does not end with '\n'.
You might try:
def readSOMNETM(inputName):
input = open(inputName, "r")
result = []
for line in input:
fields = line.split()
try:
data = fields[1] + fields[2] + fields[7]
except:
print repr(line)
print fields
raise ValueError
result.append(data)
input.close()
return result
