Q1) What is Python?

Ans: Python is a high-level and object-oriented programming language with unified semantics designed primarily for developing apps and the web. It is the core language in the field of Rapid Application Development (RAD) as it offers options such as dynamic binding and dynamic typing.                                                                                                                                                                                                          

Q2) What are the benefits of Python?

Ans: The benefits of Python are as follows: 

Speed and Productivity: 

Utilizing the productivity and speed of Python will enhance the process control capabilities and possesses strong integration.

Extensive Support for Libraries: 

Python provides a large standard library that includes areas such as operating system interfaces, web service tools, internet protocols, and string protocols. Most of the programming tasks are already been scripted in the standard library which reduces effort and time.

User-friendly Data Structures: 

Python has an in-built dictionary of data structures that are used to build fast user-friendly data structures.

Existence of Third Party Modules: 

The presence of third party modules in the Python Package Index (PyPI) will make Python capable to interact with other platforms and languages.

Easy Learning: 

Python provides excellent readability and simple syntaxes to make it easy for beginners to learn.

Q3) What are the key features of Python?

Ans: The following are the significant features of Python, and they are:

Interpreted Language: 

Python is an interpreted language that is used to execute the code line by line at a time. This makes debugging easy.

Highly Portable: 

As Python can run on different platforms such as Unix, Macintosh, Linux, Windows, and so on. So, we can say that it is a highly portable language.

Extensible: 

It ensures that the Python code can be compiled on various other languages such as C, C++ and so on.

GUI programming Support: 

It implies that Python provides support to develop graphical user interfaces
 

Q4) What type of language is Python? Programming or Scripting?

Ans: Python is suitable for scripting, but in general it is considered as a general-purpose programming language.

Q5) What are the applications of Python?

Ans: The applications of Python are as follows:

GUI based desktop applications
Image processing applications
Business and Enterprise applications
Prototyping
Web and web framework applications

Q6) Define PYTHON PATH?

Ans: PYTHONPATH is an environmental variable that is used when we import a module. Suppose at any time we import a module, PYTHONPATH is used to check the presence of the modules that are imported in different directories. Loading of the module will be determined by interpreters.

Q7) What are the two major loop statements?

Ans: for and while

Q8) What do you understand by the term PEP 8?

Ans: PEP 8 is the Python latest coding convention and it is abbreviated as Python Enhancement Proposal. It is all about how to format your Python code for maximum readability.

Q9) What are the built-in types available in Python?
Ans: The built-in types in Python are as follows:

Integer
Complex numbers
Floating-point numbers
Strings
Built-in functions

Q10) What is the difference between .py and .pyc files?
Ans: .py files are Python source files. .pyc files are the compiled bytecode files that are generated by the Python compiler.
