2.15 LAB: Musical note frequencies

 

On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * 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}')
