Python - how to delete an item from a nested list, file input

Asked by sara_bellum in Python Scripting Language, Linux

Tags: Python

The python readlines() function gives me a list, output[], from file and I want to delete any line from output[] that is short the required number of list elements (14).  I can print the index values of the lines concerned, but I can't delete the lines themselves - the objects are either unsubscriptable or don't support item deletion. Help!

output = src.readlines()
 
index = 0
for index, lines in enumerate(output):
   lines = lines.split(',', 13)
   if (len(lines) < 14):
       print index  # prints correct index value 
       del index     # or output2[index] etc, fails
   else:
       index +=1
