Donald pointed out the first error. (actually there are 3 such
spelling errors).<br>
<br>
When you get "name xxx is not defined" use your editor's find
feature to find where the name is defined. In this case you would
not find it which should lead you to the problem.<br>
<br>
When you fix that you will then get<br>
TypeError: 'str' object is not callable<br>
on the same line of code.<br>
<br>
Do you see why?<br>
<br>
When you fix that you will then get either<br>
ValueError: invalid literal for int() or<br>
ValueError: int() base must be >= 2 and <= 36<br>
<br>
Before returning with "why" attempt to apply the error message to
the code to see what the problems are.<br>
Look up int() in the Python documentation <br>

way of thinking is firstly I need to fix line 29 which is
