How to catch OverflowError Exception in Python?
When an arithmetic operation exceeds the limits of the variable type, an OverflowError is raised. Long integers allocate more space as values grow, so they end up raising MemoryError. Floating point exception handling is not standardized, however. Regular integers are converted to long values as needed.
Example
Given code is rewritten to catch exception as follows
i=1 try: f = 3.0**i for i in range(100): print i, f f = f ** 2 except OverflowError as err: print 'Overflowed after ', f, err
Output
We get following OverflowError as output as follows
C:/Users/TutorialsPoint1/~scratch_1.py Floating point values: 0 3.0 1 9.0 2 81.0 3 6561.0 4 43046721.0 5 1.85302018885e+15 6 3.43368382029e+30 7 1.17901845777e+61 8 1.39008452377e+122 9 1.93233498323e+244 Overflowed after 1.93233498323e+244 (34, 'Result too large')
