QUESTIONS

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 It eliminated outdated practices and promoted more modern and intuitive programming methods.

Which of the following character is used to give single-line comments in Python?

Right Answer:

To write single-line comments in Python use the Hash character (#) at the beginning of the line. It is also called number sign or pound sign. To write multi-line comments, close the text between triple quotes.
Example: “”” comment
text “””

All keywords in Python are in _________

Right Answer:

True, False and None are capitalized while the others are in lower case.

What will be the output of the following Python code?

i = 1
while True:
if i % 3 == 0:
break
print(i)

i += 1

Right Answer:

SyntaxError, there shouldn’t be a space between + and = in +=.

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.

Can Python 3 be considered a general-purpose language, and why?

Right Answer:

Yes, Python 3 is considered a general-purpose language because it can be used for a wide variety of applications, from web development to scientific computing, making it versatile and adaptable to different tasks.

Which keyword is used for function in Python language?

Right Answer:

The def keyword is used to create, (or define) a function in python.

Which of the following is used to define a block of code in Python language?

Right Answer:

In Python, to define a block of code we use indentation. Indentation refers to whitespaces at the beginning of the line.

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 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.
