1. What is Python? What are the benefits of using Python
Python is a high-level, interpreted, general-purpose programming language. Being a general-purpose language, it can

automatic memory management which help in modelling real-world problems and building applications to solve these
Benefits of using Python:
Python is a general-purpose programming language that has a simple, easy-to-learn syntax that emphasizes reada
reduces the cost of program maintenance. Moreover, the language is capable of scripting, is completely open-sou
party packages encouraging modularity and code reuse.
Its high-level data structures, combined with dynamic typing and dynamic binding, attract a huge community of d

2. What is a dynamically typed language?
Before we understand a dynamically typed language, we should learn about what typing is. Typing refers to type-chec
languages. In a strongly-typed language, such as Python, "1" + 2 will result in a type error since these languages don

Type-checking can be done at two stages -
Static - Data Types are checked before execution.
Dynamic - Data Types are checked during execution.

PEP stands for Python Enhancement Proposal. A PEP is an official design document providing information to the Pyth
describing a new feature for Python or its processes. PEP 8 is especially important since it documents the style guidelin

Every object in Python functions within a scope. A scope is a block of code where an object in Python remains relevant

without any prefix. A few examples of scope created during code execution in Python are as follows:
A local scope refers to the local objects available in the current function.
A global scope refers to the objects available throughout the code execution since their inception.
A module-level scope refers to the global objects of the current module accessible in the program.
An outermost scope refers to all the built-in names callable in the program. The objects in this scope are searche
referenced.
Note: Local scope objects can be synced with global scope objects using keywords such as global.
6. What are lists and tuples? What is the key difference between the two?
Lists and Tuples are both sequence data types that can store a collection of objects in Python. The objects stored in b
have different data types. Lists are represented with square brackets ['sara', 6, 0.19] , while tuples are represen
('ansh', 5, 0.97) .
But what is the real difference between the two? The key difference between the two is that while lists are mutable, tu
are immutable objects. This means that lists can be modified, appended or sliced on the go but tuples remain constan
modified in any manner. You can run the following example on Python IDLE to confirm the difference:
my_tuple = ('sara', 6, 5, 0.97)
my_list = ['sara', 6, 5, 0.97]
print(my_tuple[0]) # output => 'sara'
print(my_list[0]) # output => 'sara'
my_tuple[0] = 'ansh' # modifying tuple => throws an error
my_list[0] = 'ansh' # modifying list => list modified
print(my_tuple[0]) # output => 'sara'
print(my_list[0]) # output => 'ansh'
