To handle an error in Python is possible with try except block. The entire block is try except else finally. But, in most of the Python scripts you will randomly come across else finally block.
Error handling is in terms of if any error arise then what are the alternate operations that Python should do. For example, if a number is in string format then "TypeError" will arise in try block. In this case we can say Python to convert string to number format in except block
With try except we can use Python's built in exceptions as well as we can create our own user defined exceptions as well. These exceptions will be used to identify an error type and take the decisions accordingly.
