Index error list index out of range abaqus manual

I try to get a list of number of cycles in time history, but I could not get the list and it show me that indexerror, could you please help me to fix it in ignition 8.1 You add items with the append method on the list object eg Sum_w.append("new item"). You haven't identified which row has the error either. In Python, lists, tuples are indexed. It means each value in a tuple is associated with index position (0 to n-1) to access that value. Where N represent the total number of values in list or tuple. When user try access an item in a tuple that is out of range the Python returns an error that says " IndexError IndexError: list index out of range. This particular traceback has two levels. Containers like lists and dictionaries will generate errors if you try to access items in them that do not exist. For lists, this type of error is called an IndexError; for dictionaries, it is called a KeyError. But in the end, few lines show index error as quoted above (like if I have 10 input IDs, I get the output for 7 of them, the other three won't run as I get Index error). Please see my code below and help with the solution. My input is a list of PubChem CIDs, nothing else. We discussed single positional indexer is out-of-bounds and in that blog post, it was related to referencing indexes for rows that do not exist. In this blog post, the error relates to referencing the index for columns that do not exist. Lets walk through the code below and where the problem arises. The error is "IndexError: list index out of range" for "D.append(cells[0].find(text=True))". I have checked the list indices for "cells', which gives me 0,1,2, so should be no problem. Could anyone suggest any ideas on solving this issue?
