Homework Help: Questions and Answers: Goal: Learn to write simple loops. Assignment: Write a code snippet that reads an integer value from standard input and stores it in a variable n. Then, write a while loop that prints to the screen all the numbers from 2 to n that are multiples of 7. 1f, for example, the user inputs the value 29 for n, your program should produce the following output (user input in bold):
Insert an integer value: 29
7 is a multiple of 7
14 is a multiple of 7
21 is a multiple of 7
28 is a multiple of 7
Answer:
First, let’s write a code to read an integer from standard input and store it in a variable n.
Input Handling: We need to read an integer value from the user. In Python, we use the input() function to achieve this.
Convert Input: The value entered by the user is treated as a string by default. We need to convert it into an integer using int().
Initialize Loop Variable: To start finding multiples of 7, we should start at 7 and proceed through all values less than or equal to n. We can achieve this by initializing a variable with value 7.
While Loop Logic: The condition of the while loop should ensure that the loop runs as long as the current number is less than or equal to n.
Print Output: Inside the loop, we will print the current value followed by “is a multiple of 7”.
Update Loop Variable: Increase the loop variable by 7 each time to get the next multiple of 7.
Complete Code:
# Step 1: Get user input and convert to integer
n = int(input("Insert an integer value: "))
# Step 2: Initialize loop variable
current = 7
# Step 3: Loop through multiples of 7
while current <= n:
print(f"{current} is a multiple of 7")
current += 7
Explanation:
Input Handling and Conversion:
n = int(input("Insert an integer value: "))
This reads an integer value from the user.
Loop Initialization:
current = 7
We start from 7 because we want to print multiples of 7 from 2 to n.
While Loop:
while current <= n:
The loop will run until current is greater than n.
Print Statement:
print(f"{current} is a multiple of 7")
This prints the current value along with the message.
Update Loop Variable:
current += 7
This ensures the next value to be checked is the next multiple of 7.
Example Run:
If the user inputs 29:
Insert an integer value: 297 is a multiple of 714 is a multiple of 721 is a multiple of 728 is a multiple of 7
This code will produce the exact output format requested in the assignment. When you run this code and enter 29, it will produce the output shown in the example.
