What is the use of try, except, finally and raise in Error Handling.

Python makes use of try, except and finally blocks for error handling. Try block is used to execute the code until an error occurs. We can make use of an except block to receive control which will receive control after all errors, or one can use specific exception handling blocks for various error types. Control is transferred to the appropriate except block. In all cases, the finally block is executed. Raise may be used to raise your own exceptions.
In case of error handling, Python uses try, except, finally and raise blocks.

• Use of try block helps in executing the code until an error arises.
• Use of except block helps in getting the control which further get control after each and every errors, or simply you can utilize particular exception handling blocks for different error types. Control is moreover moved to the suitable except block.
• The finally block is executed in each case.
• You can raise our own exception as well with the help of raise block.
