Write a program that asks the user to enter a distance in kilometers
Q1. Write a program that asks the user to enter a distance in kilometers, and then converts that distance to miles. The conversion formula is as follows:
Miles Kilometer x 0.6214
Submission for Q1:
1. A Python code file
2. Screenshot of the Running program
Q2. Write the following codes
Submission of Q2 (All parts a, b, and c):
1. A summary of the program, what does the program do
2. Screenshot of the Running program
a). def message():
print('I am Arthur,')
print('King of the Britons.')
message()
b) def main():
print('I have a message for you.')
message()
print('Goodbye!')
def message():
print('I am Arthur,')
print('King of the Britons.')
main()
c)
def area(width, length):
return width * length
def perimeter(width, length):
return 2 * (width + length)
def main():
width = float(input("Enter the rectangle's width: "))
length = float(input("Enter the rectangle's length: "))
print('The area is', area(width, length))
print('The perimeter is', perimeter(width, length))
main()
Sample Solution
I'm unable to create screenshots and code files directly, but I can provide the code and descriptions for Q1 and Q2.
Q1:
Python code:
Python
def kilometers_to_miles():
try:
kilometers = float(input("Enter the distance in kilometers: "))
miles = kilometers * 0.6214
print("%.2f kilometers is equal to %.2f miles." % (kilometers, miles))
except ValueError:
print("Invalid input. Please enter a numerical value for kilometers.")
kilometers_to_miles()
Code explanation:
- Defines a function
kilometers_to_miles(). - Prompts the user for input using
input(). - Uses
float()to convert input to a float. - Converts kilometers to miles using the formula.
- Prints the result using a formatted string with
%.2ffor two decimal places. - Uses
try-exceptto handle invalid input.
Q2:
a) Summary:
- Defines a function
message()that prints two lines of text. - Calls
message()directly to execute it.
b) Summary:
- Defines two functions:
main()andmessage(). main()callsmessage()and prints additional text.- Function calls are controlled by execution order.

Q2:
a) Summary:
- Defines a function
message()that prints two lines of text. - Calls
message()directly to execute it.
b) Summary:
- Defines two functions:
main()andmessage(). main()callsmessage()and prints additional text.- Function calls are controlled by execution order.
c) Summary:
- Defines three functions:
area(),perimeter(), andmain(). area()andperimeter()calculate the rectangle's properties.main()gets user input, calls the other functions, and prints results.- Demonstrates function calls with arguments and return values.
