Question

Python shell executes the _______ one at a time.  (a) Scripts (b) Commands (c) Keywords (d) Calculations​

Answer 1

B) Commands is the correct answer

Answer 2

Explanation:

The answer is (b). The Python shell executes commands one at a time. Scripts are a collection of commands, but they are executed as a whole. Keywords are reserved words in Python, and calculations are performed on data.

The Python shell is a command-line interpreter that allows you to interact with Python. You can type commands into the shell, and the shell will execute them one at a time. This makes it easy to test small pieces of code or to debug larger programs.

Here is an example of how to use the Python shell:

```python

>>> print("Hello, world!")

Hello, world!

>>> 2 + 2

4

>>> exit()

```

In the first line, we type the command `print("Hello, world!")`. The shell executes this command, and the output is displayed on the screen. In the second line, we type the command `2 + 2`. The shell executes this command, and the output is 4. In the third line, we type the command `exit()`. This command tells the shell to quit.

I hope this helps! Let me know if you have any other questions.
