Right Answer:
Many languages have been implemented using both compilers and interpreters, including C, Pascal, and Python.

Right Answer:
Python's clear and straightforward syntax contributes to its popularity, as it lowers the barrier to entry for new programmers. The ease of learning and using Python encourages more people to adopt it for various programming tasks.
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 It eliminated outdated practices and promoted more modern and intuitive programming methods.
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 +=.
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.
x<<2
Right Answer:
The binary form of 1 is 0001. The expression x<<2 implies we are performing bitwise left shift on x. This shift yields the value: 0100, which is the binary form of the number 4.
Right Answer:
In Python, to define a block of code we use indentation. Indentation refers to whitespaces at the beginning of the line.
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.
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.
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.
