QUESTIONS

Why is backward compatibility an important consideration in programming language development?

Right Answer:

Backward compatibility is important because it allows users to run older code without modification. This is crucial for maintaining existing applications and systems, ensuring that updates do not break functionality.

What significant changes did Python 3.0 introduce?

Right Answer:

Python 3.0 aimed to correct inconsistencies and design flaws in the language, even if it meant breaking backward compatibility. It eliminated outdated practices and promoted more modern and intuitive programming methods.

Python supports the creation of anonymous functions at runtime, using a construct called __________

Right Answer:

Python supports the creation of anonymous functions (i.e. functions that are not bound to a name) at runtime, using a construct called lambda. Lambda functions are restricted to a single expression. They can be used wherever normal functions can be used.

How does Python's interpreted nature benefit developers?

Right Answer:

Python's interpreted nature allows for quick iteration and prototyping, which is invaluable in research and development phases. Developers can test and modify their code on the fly without the need for a separate compilation step.

Which of the following functions can help us to find the version of python that we are currently working on?

Right Answer:

The function sys.version can help us to find the version of python that we are currently working on. It also contains information on the build number and compiler used. For example, 3.5.2, 2.7.3 etc. this function also returns the current date, time, bits etc along with the version.

What role do standard libraries play in Python's functionality?

Right Answer:

Standard libraries in Python provide a rich set of modules and functions that allow developers to perform common tasks without needing to write code from scratch. This enhances productivity and makes Python suitable for a broad range of applications.

Which of the following is the correct extension of the Python file?

Right Answer:

‘.py’ is the correct extension of the Python file. Python programs can be written in any text editor. To save these programs we need to save in files with file extension ‘.py’.

What is the order of precedence in python?

Right Answer:

For order of precedence, just remember this PEMDAS (similar to BODMAS).

What is the significance of Python's design for readability?

Right Answer:

The design for readability in Python makes the language more accessible to beginners and promotes good coding practices. This leads to easier collaboration among developers and simplifies maintenance of code.

What was the primary goal of Python 1.0, released in 1991?

Right Answer:

The primary goal of Python 1.0 was to create a language designed for readability, simplicity, and ease of use, aiming to balance between low-level languages (like C) and shell scripting.
