TypeErrors are caused by combining the wrong type of objects, or calling a function with the wrong type of object.
Example
import sys try : ny = 'Statue of Liberty' my_list = [3, 4, 5, 8, 9] print my_list + ny except TypeError as e: print e print sys.exc_type
Output
can only concatenate list (not ""str") to list <type 'exceptions.TypeError'>
