Explain modes in Python Programming Environment?
Script Mode: This mode is used to compile and save Python programs which is not possible in the Interactive mode.
Interactive Mode: This mode can be thought of as a scratchpad to check out codes in Python Environment.
In order to make it executable, we should prefer Script Mode.
What is Slicing in Python?
Slicing is a terminology hat is used to generate sliced or modified output from Lists and Tuples.
Enlist commonly used Classes in games Module in livewires Package?
The commonly used Classes in Games Module under Livewires Package are as follows:

What is the output of print list if list = [ ‘abcd’, 786 , 2.23, ‘john’, 70.2 ]?
It will print concatenated lists. Output would be [ ‘abcd’, 786 , 2.23, ‘john’, 70.2 ].
What is the output of print list[0] if list = [ ‘abcd’, 786 , 2.23, ‘john’, 70.2 ]?
It will print first element of the list. Output would be abcd.
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.
What is Tkinter in Python and what is it used for?
Tkinter is a Python module available for Python programmers for development of Graphical User Interface (GUI) programs. Tkinter module is used to import the methods required for creation of GUI in a Python program.
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.
Why And When Do You Use Generators In Python?
A generator in Python is a function which returns an iterable object. We can iterate on the generator object using the <yield> keyword. But we can only do that once because their values don’t persist in memory, they get the values on the fly.
Generators give us the ability to hold the execution of a function or a step as long as we want to keep it. However, here are a few examples where it is beneficial to use generators.
We can replace loops with generators for efficiently calculating results involving large data sets.
Generators are useful when we don’t want all the results and wish to hold back for some time.
Instead of using a callback function, we can replace it with a generator. We can write a loop inside the function doing the same thing as the callback and turns it into a generator.

How the string does get converted to a number?
- To convert the string into a number the built-in functions are used like int() constructor. It is a data type that is used like int (‘1’) ==1.
- float() is also used to show the number in the format as float(‘1’)=1.
- The number by default are interpreted as decimal and if it is represented by int(‘0x1’) then it gives an error as ValueError. In this the int(string,base) function takes the parameter to convert string to number in this the process will be like int(‘0x1’,16)==16. If the base parameter is defined as 0 then it is indicated by an octal and 0x indicates it as hexadecimal number.
- There is function eval() that can be used to convert string into number but it is a bit slower and present many security risks like __import__('os').system("rm -rf$HOME") - use of this will delete the home directory of the system.
What is the output of print str[2:5] if str = ‘Hello World!’?
It will print characters starting from 3rd to 5th. Output would be llo.
What is the output of print str[2:] if str = ‘Hello World!’?
It will print characters starting from 3rd character. Output would be llo World!.
What is the output of print str * 2 if str = ‘Hello World!’?
It will print string two times. Output would be Hello World!Hello World!.
