How to pass argument to an Exception in Python?

An exception can have an argument, which is a value that gives additional information about the problem. The contents of the argument vary from exception to exception. You capture an exception's argument by supplying a variable in the except clause as follows

Example

try:
b=float(56+78/0)
except Exception, Argument:
print 'This is the Argument\n', Argument

Output

The output obtained is as follows

This is the Argument
integer division or modulo by zero

If you write the code to handle a single exception, you can have a variable follow the name of the exception in the except statement. If you are trapping multiple exceptions, you can have a variable follow the tuple of the exception.

This variable receives the value of the exception mostly containing the cause of the exception. The variable can receive a single value or multiple values in the form of a tuple. This tuple usually contains the error string, the error number, and an error location.
