Questions & Answers

2. Python is a general-purpose, high-level programming
language. It is the most popular language among developers
and programmers as it can be used in Machine Learning, Web
Development, Image Processing, etc. Currently a lot of tech
companies like Google, Amazon, Facebook, etc. are using
Python and hire a lot of people every year.
What is Python?

3. Python uses Tim Sort algorithm for sorting. It’s a stable sorting whose
worst case is O(N log N). It’s a hybrid sorting algorithm, derived from
merge sort and insertion sort, designed to perform well on many kinds
of real-world data.
Which sorting technique is used by sort()
and sorted() functions of python?

4. Lists are Mutable datatype.
Lists consume more memory
The list is better for performing operations, such as insertion and
deletion.
Implication of iterations is Time-consuming
Tuples are Immutable datatype.
Tuple consume less memory as compared to the list
Tuple data type is appropriate for accessing the elements
Implication of iterations is comparatively Faster
Let’s analyze the differences between List and Tuple:
List
Tuple
Differentiate between List and Tuple?

5. PEP 8 is a Python style guide. It is a document that
provides the guidelines and best practices on how
to write beautiful Python code. It promotes a very
readable and eye-pleasing coding style.
What is PEP 8?
