Thank you for trying to help, Martin. So:

so, I do not quite control the format of the file I am trying to parse.
it has the format:
"str1","str2",....,"strN" => more stuff
:
in some cases there is just one "str" which is what created me problem.
The first "str1" has special meaning and, at times, it can be alone.
The way I handle this is:
parts = line.strip().split(" => ")
tokens = eval(parts[0])
if type(tokens) == str: #Handle case that there's only one token
columns.add(tokens)
rowTokenString = "__Empty__"
rows.add(rowTokenString)
value = parts[1][:2]
addCell(table, rowTokenString, tokens, value)
else:
columns.add(tokens[0])
rowTokenString = '"'+'","'.join(tokens[1:]) + '"'
rows.add(rowTokenString)
value = parts[1][:2]
addCell(table, rowTokenString, tokens[0],value)
which admittedly is not very elegant. If you have suggestions on how to avoid the use
of eval() and still achieve the same, I would be delighted to hear them
