input: Write a function to edit the given python code to prompt the user to enter the value of radius to calculate the area of a circle. If the code runs correctly, it should print the area of the circle based on the radius provided by the user.
  
  assert calculate_circle_area()==None
  # Expected output when radius is 5:
  # Please enter the radius of the circle: 5
  # The area of the circle is: 78.5
  
  assert calculate_circle_area()==None
  # Expected output when radius is 7:
  # Please enter the radius of the circle: 7
  # The area of the circle is: 153.86
output: def calculate_circle_area():
      radius = float(input("Please enter the radius of the circle: "))
      area = 3.14 * radius * radius
      print(f"The area of the circle is: {area}")
