For later use, you should look for numpy.
This allows for example broadcasting.

import numpy as np


def gen_signal():
    amplification = 10.5
    time_base = np.linspace(0, np.pi * 2, 1_000_000)
    signal = np.sin(time_base * 1440) # 1440 Hz
    signal += np.sin(time_base * 440) # 440 Hz
    signal += np.sin(time_base * 20) # 20 Hz
    signal += np.sin(time_base * 44) # 44 Hz
    signal *= amplification
    return signal

But you should also know the Python primitives.
I see often, that people are using this libraries,
but they don't know how they can do this without this library.

The benefit of numpy is, that it's implementation is in C and highly optimized.
But for small lists it's ok to use a normal list comprehension or if you want to save memory, a generator expression.
