Python Try - Except

It is used for error handling in python, try is used for caught and except is used to handle these errors.

 

Python has some built-in exceptions which stop the program execution but these not affect the output result, so to reduce these error use try-except, which handle the process and program running properly.

​

There are two types of error which are handled by this:

​

  • Syntax Error

  • Exception

​

The program contains several types of exception which are handled by this:

​

  • IOError 

  • KeyboardInterrupt

  • ValueError 

  • EOFError 

  • ImportError 

​

By this program divided into the three parts:

  • try

  • Except

  • finally

​

We can easily understand it with the help of the given below example:

>>> Import sys       #use to get the type of exception

 

>>> list = [1,2,3]

>>> for a in list:

>>>     try:

>>>         print(“value is”)

>>>         result = a

>>>         break

>>>     catch:

>>>         print(“enter another value”)

>>> print(“the result is”, a)
