Instructions Write a program to enter a number and test if it is greater than 45.6. If the number entered is greater than 45.6, the program needs to output the phrase Greater than 45.6. Sample Run Enter a number: 90 Sample Output Greater than 45.6
The Correct Answer and Explanation is:
Here’s a Python program that fulfills the task:
# Program to check if a number is greater than 45.6
# Input from the user
number = float(input("Enter a number: "))
# Condition check
if number > 45.6:
print("Greater than 45.6")
Explanation (300 words):
This program is designed to compare a user-input number with the decimal value 45.6 and check whether it is greater than this threshold. Let’s break down how the program works and why it’s structured this way.
First, the program uses the input() function to prompt the user with the message “Enter a number: “. The input() function collects data from the user in the form of a string. To compare the input as a number, we must convert it from a string to a numeric type. In this case, we use the float() function to allow decimal input (e.g., 45.7, 90.0, etc.) instead of only integers. This ensures that the program works correctly even if the user inputs fractional values.
Once the number has been successfully read and converted to a float, the program evaluates whether it is greater than 45.6 using a simple if statement:
if number > 45.6:
If this condition evaluates to True (i.e., the input is greater than 45.6), the program proceeds to execute the indented line beneath the if statement, which prints the message:
“Greater than 45.6”.
This message is printed to the screen using the print() function.
If the user enters a number equal to or less than 45.6, nothing will be printed because the condition fails, and there is no else clause to handle other cases.
This program is a basic introduction to conditional logic, numeric comparison, and user interaction in Python. It helps beginners understand how programs can make decisions based on user input.
