How to calculate slope using python with the data below?

Question

My data looks like this:

Can you please let me know how to calculate slope in this case when there blank values?

Answer 1

If you get an error, you can just use the try, except tool in python. It first tries the statement you give it, and if it gives an error back you can skip that exception, print an error, etc.

try: 
   slope = [slope calculation]
except:
   print 'not enough data'
