RL Python Basics Quiz 1

Choose the correct statement

• The standard python interpretor is written in C and python

• The standard python compiler is written in C++

• The standard python interpretor is written in C++

• The standard python compiler is written in python

Answer explanation

Yes, certain parts of the standard Python interpreter are written in Python itself. The Python interpreter is implemented in C, which provides the core execution engine and interfaces with the underlying operating system. However, Python also includes a significant amount of code written in Python for various purposes.

For example, the Python standard library, which provides a wide range of modules and functionalities, is primarily written in Python. This includes modules like os, sys, math, datetime, and many others. These modules are implemented using Python code and often rely on the underlying C-based interpreter for performance-critical operations.

Additionally, the Python language itself is defined using Python code. The Python compiler and parser are written in Python, allowing the interpreter to understand and execute Python source code. The ast (Abstract Syntax Trees) module, which provides tools for working with the parsed structure of Python code, is also implemented in Python.

It's worth noting that although parts of the interpreter and standard library are written in Python, the core execution engine that interprets and executes the Python bytecode is implemented in C for performance reasons. This combination of C and Python allows Python to balance performance and flexibility.

1. What will be the output of the following code snippet?

3. x = 10

4. y = 5

5. z = x / y

6. print(z)

• 2.0

• 2

• 2.5

• 5

x = 5

y = 10

print(x + y * 2)

• 30

• 25

• 35

• 20

d = len("Mountain Duke")

print("a","b", sep="-", end="^")

print("c",d)

• a - b ^

  c 13

• a-b^c 12

• a-b^c 13

• a-b^

  c 12

d = len("Mountain Duke")

print("a","b", sep="-", end="^")

print("c",d)

• a - b ^

  c 13

• a-b^c 12

• a-b^c 13

• a-b^

  c 12

What is the output of the code
x = 5

x += 2

x *= 3

x //= 2

print(x)

• 11

• 10

• 12

• 13

What is the output of

print("hello this is my quiz %d"% (10%9))

• hello this is my quiz 1

• hello this is my quiz 10%9

• hello this is my quiz %d

• We cannot perform modulo of a string with an integer.

x = 10

y = x**2 - x

z = "x is smaller" if x > y else ("y is master" if y > x else "x and y are dummy") print(z)

• x is smaller

• y is master

• x and y are dummy

• There will be an error

What will be the output if you execute this in a Jupyter Notebook python cell ?

6 > 7 and 7 < 6 or 13 == 13

• No output

• True

• False

• Will produce some error
