TypeError: ‘int’ object is not subscriptable – Trying To Create A Graph

This is creating a single integer that’s the concatenation of all the numbers in CaseNumberList, not a list of integers:

IntCaseNumberList = int("".join(str(i) for i in CaseNumberList))

So when you try to ue IntCaseNumberList[i], it doesn’t work because it’s a number, not a list.

To create a list of integers, you need to call int() inside in a list comprehension:

IntCaseNumberList = [int(i) for i in CaseNumberList]

You could also just put integers directly into CaseNumberList in the first place, then you wouldn’t need to make a new list. Change

CaseNumberList.append(CaseNumber)

to

CaseNumberList.append(int(CaseNumber))
