Question
On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * r, where n is the distance (number of keys) from that key, and r is 201/12), 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_valuel: .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 = 2112) using the pow function (remember to import the math module). Then use that r in subsequent statements that use the formula fn = f0 * rn with n being 1, 2, 3, and finally 4.

Expert Solution
Step 1

Python code:

f=int(input("Enter frequency: "))
r=pow(2,1/12)

for i in range(4):
    fn=f*pow(r,i+1)
    float_decimal = "{:.2f}".format(fn)
    print(float_decimal, end = " ")
