Question

Hello I need help with this problem. I keep getting it wrong. I am using python.

2.17 LAB: Musical note frequencies
On a piano, a key has a frequency, say fo. Each higher key (black or white) has a frequency of fo* rn, where n is the distance (number of
keys) from that key, and r is 2(1/12). Given an initial key frequency, output that frequency and the next 4 higher key frequencies.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print (f' {your_value1: .2f} {your_value2:.2f} {your_value3:.2f} {your_value4: .2f} {your_value5:.2f}')
Ex: If the input is:
440
(which is the A key near the middle of a piano keyboard), the output is:
440.00 466.16 493.88 523.25 554.37
Note: Use one statement to computer = 2(1/12) using the pow function (remember to import the math module). Then use that r in
subsequent statements that use the formula fn = f0 *r" with n being 1, 2, 3, and finally 4.

Expert Solution

Step 1

The source code of the program

import math

key_input = float(input())

power = 1.05946309436
distance = pow(power, 0)
distance2 = pow(power, 1)
distance3 = pow(power, 2)
distance4 = pow(power, 3)
distance5 = pow(power, 4)

value1 = key_input * distance
value2 = key_input * distance2
value3 = key_input * distance3
value4 = key_input * distance4
value5 = key_input * distance5

print('{:.2f} {:.2f} {:.2f} {:.2f} {:.2f}'.format(value1, value2, value3, value4, value5))
