Complete Python Scripting for Automation - try except else and finally usage

The video tutorial explains the use of try-except blocks in Python for error handling. It covers handling known exceptions, the role of the finally block, and the use of the else block. The tutorial also provides a complete syntax for try-except-else-finally and demonstrates how these blocks execute under different conditions.

What is the primary purpose of a try-except block in Python?

• To handle exceptions and prevent program crashes

• To execute code only if an error occurs

• To debug code automatically

• To ensure code runs faster

Which exception is raised when a variable is not defined in Python?

• TypeError

• ValueError

• NameError

• IndexError

What is the role of the 'finally' block in a try-except structure?

• To execute regardless of whether an exception is raised or not

• To execute only if no exception is raised

• To execute only if an exception is raised

• To execute before the try block

When does the 'else' block execute in a try-except-else-finally structure?

• Only if no exception is raised

• Only if an exception is raised

• Always, regardless of exceptions

• Only if the finally block executes

Which blocks are optional in a try-except-else-finally structure?

• else and finally

• try and finally

• try and except

• except and else

What happens if an exception occurs in the try block and there is an else block?

• The else block will execute

• The else block will not execute

• The program will terminate immediately

• The finally block will not execute

In a try-except structure, what is the correct order of blocks?

• try, finally, except, else

• try, except, else, finally

• except, try, finally, else

• finally, try, except, else
