Python try except example program

• Exceptions are the objects representing the logical errors that occur at run time.
• When python script encounters any error at run time it will create python object.
• So we need to handle this situation otherwise python program will terminates because of that run time error ( Exception Object).
• So we can handle this by assigning this python exception object to corresponding python class.
• For that Python provides try and except blocks to handle exceptions.
• In try block we need to keep all the statements which may raise exceptions at run time.
• except block will catch that exception and assigns to corresponding error class.
• Lets see an example python program on exception handling using try and except blocks.

#1: Example Program to handle exception using try and except blocks in python programming.

1. #use of try_catch in functions:
2. def f():
3.    x=int(input("enter some number: "))
4.    print(x)
5. 
   
6. try:
7.     f()
8.     print("no exception")
9. except ValueError as e:
10.     print("exception: ", e)
11.     print("Rest of the Application")

Output

1. enter some number: 2
2. 2
3. no exception
4. >>> 
5. 
   
6. 
   
7. 
   
8. enter some number: "python"
9. exception:  invalid literal for int() with base 10: '"python"'
10. Rest of the Application
11. >>>
