Question

I’m very new to python so I have very simple doubt. Here is my code:

a=sri

try:
    print a
except Exception:
    print 'you have not put quotes for string'
else:
    print 'dont know what error it is'

How to write a manual exception/error handling for this?

Answer 1

The code for which you need to handle errors should be written in the try clause. The except clause is where you write how to handle the possible exceptions.

try:
    a=sri
    print a
except Exception:
    print 'you have not put quotes for string'

More on try statement from python docs.

The try statement works as follows.

• First, the try clause (the statement(s) between the try and except
  keywords) is executed.
• If no exception occurs, the except clause is
  skipped and execution of the try statement is finished.
• If an
  exception occurs during execution of the try clause, the rest of the
  clause is skipped. Then if its type matches the exception named after
  the except keyword, the except clause is executed, and then execution
  continues after the try statement.
• If an exception occurs which does
  not match the exception named in the except clause, it is passed on to
  outer try statements; if no handler is found, it is an unhandled
  exception and execution stops with a message as shown above.
