overview

<
p
>
The dictionary returned by <
code
>locals()</
code
> is not a view of the function's locals, but a copy.
Therefore, modification of the dictionary returned from <
code
>locals()</
code
> will not modify the local
variables of the function.

<
recommendation

<
p
>If the intention is to modify a local variable, then do so directly.

<

>In this example, rather than assigning to the variable <
code

code
>locals()</

is modified.
