Donald pointed out the first error. (actually there are 3 such spelling 
errors).

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.

When you fix that you will then get
TypeError: 'str' object is not callable
on the same line of code.

Do you see why?

When you fix that you will then get either
ValueError: invalid literal for int() or
ValueError: int() base must be >= 2 and <= 36

Before returning with "why" attempt to apply the error message to the 
code to see what the problems are.
Look up int() in the Python documentation
