Handling an Exception

try:
   a = 2
   b = 0
   print( a/b )
   print(" Done with division...")
except ZeroDivisionError:
   print (" A ZeroDivisionError exception happened...")
finally:
   print("This line will run no matter what")

The final block will be handled no matter whether an exception will be handled or not

Handling of multiple exception types

try:
   var = 10
   print(var + " hi")
   print(var / 2)
except ZeroDivisionError:
   print("Division by zero")
except(ValueError, TypeError):
   print("Houston we have a problem...")

Catch all errors

try:
   text = ("This is a string")
   print(word / 0)
except:
   print("An exception happened")

Raise an exception on your own

print("Get ready!")
raise ValueError
print("No one executed me...")

Re-raise an exception

try:
   number = 7 / 0
except:
   print("Houston we have a problem...")
   raise
