How are exceptions handled in Python?
An Exception is raised by Python when an error occurs at program run-time. Python Exceptions can be caught using try and catch blocks. When you are suspicious of a statement, move it it into the try block and on error the control moves into the catch block and a pre-defined activity can be executed which helps to avoid an abnormal termination of the program.

A Frame in Python can be related as a storage holder for other Graphical User Interface or GUI elements such as Label, Text Entry, Text Box, Check Button, Radio Button, etc.
What is another method for Using Loops with While Loop and For Loop?
Python provides a method named as range() that provides looping constructs. It works in similar fashion as while and for loop. It takes in 2 compulsory parameters and 1 optional parameter.
What is namespace in Python?
For every variable that is introduced in Python, there is a namespace that is associated with the place holder for that particular variable. It is a place holder where a variable can be linked to the object placed.
Does Python Compiled Code contains Byte-Codes?
No. Python is primarily an Interpreted Language. However, at first the .py file is compiled to something called as Python Byte-Code which is not a file that contains Binary digits like other Programming environments. It actually contains Python specific instructions that helps in optimizing the startup speed.
Does Python Supports Switch Case statements?
No, Python does not have provision for Switch Case statements. However, it provides with an alternative called as ‘One-to-One Mapping’.
How do you create a Button Element in Python?
The Button Class is available in Tkinter Module. We first need to import it and then we can take in a frame label by the following command:

A Def is a function that can contain multiple expressions whereas a Lambda can contain only one single expression. A Def method can contain return statements whereas a Lambda cannot contain return statements. A Lambda can be used inside lists and dictionaries.
What is a Line Continuation Character in Python?
A Line continuation character in Python is the one which lets us to continue a single line of code on the next line without changing its meaning. We can do it using a Line continuation character provided by Python which is a Backslash.
Why is Finally Block used in Python Exception Handling?
A Finally Block is generally used in association with try and catch blocks in Python. A Finally Block executes itself no matter if an error occurs at run time or not. It is the default execution block in Python Exception Handling technique.
How is the memory management process in Python?
Like other programming environments, Python Programming Environment has Garbage Collection Techniques that manages the Memory efficiently. Moreover, the memory is managed by the Private Heap which is ultimately managed by the Python Memory Manager.
