Python 同时循环 output 到列表

Question

I wrote a simple code that takes as input a.wav file and then finds the frequencies and returns the corresponding note. However, in order to add some more functionality, I need the output to be a list. A simplified pseudo code of what I have looks like this:

while some condition = true:
    compute various things
    print(frequency)

It does print my frequencies correctly, however since it's in a while loop and for every note found it outputs the frequency, the output looks like this:

A2
G3
B4
A2
...

When I use list append, it returns me this:

["A2"]
["G3"]
["B4"]
["A2"]
...

Whereas I need something like this:

["A2", "G3", "B4", "A2", ...]

I really don't know how to go about this and to get my output as a list.

Answer 1

Try creating an empty list before the while loop, then appending to it within the loop:

result_list = []
while some condition = true:
    compute various things
    result_list.append(frequency)
    print(frequency)

Answer 2

Have you tried to print the list outside the while block?

result_list = []
while some condition = true:
    compute various things
    result_list.append(frequency)
print(frequency)

Answer 3

I think you should put the print statement outside the while:

result_list = []
while some condition = true:
    compute various things
    result_list.append(frequency)
print(frequency)
