Ho do I calculate area using Run Length Encoding - PYTHON

I am trying to calculate the area of a file with RLE (run Length Encoding) format numbers using PYTHON. I am having trouble with my FOR and IF statements.

I am trying to calculate the area of cells containing the value 201.

My current error:

Traceback (most recent call last):
  File "D:\2016-2017\Fall2016\SpatialDataStructures\Labs\Lab4\Area_Calc_from_RLE.py", line 68, in <module>
    if cellValuesAsIntList[i] == 201:
IndexError: string index out of range

Here is the file I am working with:

ncols         40
nrows         40
xllcorner     -2.3036649208516
