Error IndexError list index out of range and python

Question

I am executing my program to print outline 53 of an output. Is this error telling me that there aren't that many lines and therefore can not print it out?

Could anyone help to resolve this?

IndexError

The IndexError is raised when you attempt to retrieve an index from a sequence, like a list or a tuple, and the index isn’t found in the sequence. The Python documentation defines when this exception is raised:

Raised when a sequence subscript is out of range. (Source)

Here’s an example that raises the IndexError:

test = list(range(53))
test[53]

---------------------------------------------------------------------------
IndexError                                Traceback (most recent call last)
<ipython-input-6-7879607f7f36> in <module>
      1 test = list(range(53))
----> 2 test[53]

If you have a list with 53 items, the last one is thelist[52] because indexing starts at 0.
