We can raise an exception based on some condition.
For example, if we want the user to enter only odd numbers, else will raise an exception.
# Example - Raise an exception
value = int(input("Enter an odd number- "))
if value%2 == 0:
raise ValueError("Exited due to invalid input!!!")
print("Value entered is : %s" % value)
except ValueError as ex:
The output is:
Enter an odd number- 2
Exited due to invalid input!!!
Enter an odd number- 1
Value entered is : 1
