Avoid "local variable is never used" in loops?

I have lots of loops where I want to do the same task several times but not iterate through a data set. For example to spawn x amount of something, I do:

var amount
for i in range(amount):
 var scene = packedScene.instance()
 add_child(scene)

I do this quite often. Now, this leaves me with many warnings saying “Local variable i is declared but never used”. My warnings are stacking up are getting cluttered with these warnings I can’t really do anything about.

What would be the best way to avoid this? Would love for gdscript to have something like:

var amount
do amount times:
    add_child(scene)

underscore

for _i in range(amount):
    var scene = packedScene.instance()
    add_child(scene)

Thank you, I did not know that! That also solved all my “The argument ‘xxxx’ is never used in the function…”-warnings. Do you also know how to solve the warning “The function ‘connect()’ returns a value, but the value is never used”, if you don’t want to use the value?

# for tween and bool warnings - to be removed in 4
