title: Spyder does not show class instance variables in variable explorer during debugging python
body: <p>I am using Spyder v2.2.5 IDE for programming python. While debugging my python code using pdb in spyder, the IDE does not show the class instance variable in Variable Explorer. It's getting difficult to check the variable values using print statement every-time.
  Is there any way to check the class instance variable values during debugging? </p>
