Python is an interpreted language that executes statements line by line directly from source code without compilation. PEP 8 documents Python style guidelines that the community strictly follows. Comments in Python start with '#' and the line is not executed. Data types like lists are mutable and can change without changing identity, while strings are immutable and cannot change once created. Indentation is required in Python and makes code more readable. Python is a free, open source, portable language with a large standard library and community support that is used for both front-end and back-end development.

Interview Questions

2. 1.What is an Interpreted language?
• An Interpreted language executes its statements line by line.
• Languages such as Python, Javascript, R, PHP, and Ruby are prime
examples of Interpreted languages.
• Programs written in an interpreted language runs directly from the
source code, with no intermediary compilation step.

3. 2.What is PEP 8 and why is it important
• PEP stands for Python Enhancement Proposal.
• PEP 8 is especially important since it documents the style guidelines for
Python Code.
• Python open-source community requires you to follow these style
guidelines sincerely and strictly.

4. 3.What does the ‘#’ symbol do in python?
• Comments starts with a ‘#’ and python will ignore them.
• By apply the comment in python code line on that line not
executed it.
• Example: #print(“Good morning”)
• print(“Hello World”)
• Only second line of the code is executed it.

5. 4.What is the difference between a Mutable
datatype and an Immutable datatype?
• Mutable datatype:
• You can change content without changing identity.
• Ex. List, set, dictionary.
• Immutable datatype:
• You can’t change immutable objects once created.
• Ex. String, tuple, int, float, complex.

6. 5.Is Indentation Required in Python?
• Yes, indentation is required in Python.
• Indentations make the code easy to read for developers in all
programming languages.
• but in Python, it is very important to indent the code in a specific
order.
• Examples:

9. 6.What are the key features of Python?
• Free and Open Source Python is a Portable language
• Easy to code Interpreted Language
• Easy to Read Large Standard Library
• Object-Oriented Language Frontend and backend
• GUI Programming Support
• High-Level Language
• Large Community Support
• Easy to Debug

10. 7.What type of language is python?
Programming or Scripting?
• Python is capable of scripting, but in general sense, it is considered as a general-
purpose programming language.
• To know more about Scripting, you can refer to the Python Scripting Tutorial.
