input: Write a function to prompt the user to enter the value of radius and calculate the area of a circle. Use the value of Pi as 3.14 in the calculation.
  assert calculate_circle_area()=="Please enter the radius of the circle: The area of the circle is:"
  assert calculate_circle_area()=="Please enter the radius of the circle: The area of the circle is: 314.0"
  assert calculate_circle_area()=="Please enter the radius of the circle: The area of the circle is: 78.5"
  assert calculate_circle_area()=="Please enter the radius of the circle: The area of the circle is: 0.0"
output: def calculate_circle_area():
      radius = float(input("Please enter the radius of the circle: "))
      area = 3.14 * radius * radius
      return f"Please enter the radius of the circle: The area of the circle is: {area}"
