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.

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.

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:

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

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.

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.

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:

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