Question

Problem Description: You are asked to write a Python script that prompts the user to enter the number of items that should be displayed from a list.

Concept(s) to Apply:
1. for…in
2. range()
3. int()
4. input()
5. Variables
6. print()

Answer 1

The task involves writing a Python script to allow a user to input the number of items they want to display from a list. Using input(), int(), variables, a for...in loop, and range(), the script will print the specified number of items from the list.

Step-by-step explanation:

Writing a Python Script to Display Items from a List

To answer the question, you need to write a Python script that allows a user to input how many items they would like to see from a given list. The concepts to be applied are predominantly related to basic Python programming structures and functions.

The first step is to prompt the user to enter the number of items they wish to display. This is accomplished using the input() function and converting the user's input into an integer with the int() function. Variables are used to store user input and list items.

Once you have the desired number of items to display as an integer, you can use a loop to iterate through the list and print() each item. The for...in loop will be used in conjunction with the range() function to control the number of iterations based on the user's input.

Here's an example of the Python script:

# Example list of items
data = ['apple', 'banana', 'cherry', 'date', 'elderberry', 'fig', 'grape']

# Prompt the user to input the number of items to display
num_items = int(input('Enter the number of items you want to display: '))

# Print the requested number of items using a loop
for i in range(num_items):
print(data[i])

This script will accurately display the number of items from the list that the user requests, assuming that the user's request does not exceed the number of items in the list.
