• 51 highlights the problem with fluid_synth_set_chorus_speed.

chan and name are also not defined which will raise NameError if these lines of code are run.

undefined-name (F821)

Derived from the Pyflakes linter.

What it does

Checks for uses of undefined names.

Why is this bad?

An undefined name is likely to raise NameError at runtime.

Example

def double():
    return n * 2  # raises `NameError` if `n` is undefined when `double` is called

Use instead:

def double(n):
    return n * 2
