Is there a way to iterate over multiple vector variables xyz values?

Lets say I want to modify a bunch of Vector3 variables and I want to change each of their x, y, and z values independently. Right now I have to either write the same code out three times, once for each axis, or create a function and pass into it a whole ton of variables. This isn’t a big deal but it has been bothering me… It seems like there must be a way to do it!

Examples; what I am doing now:

if(foo.x > 5):
	bar.x = foo.x
	eggs.x += bar.x
	foo.x = ham.x

if(foo.y > 5):
	bar.y = foo.y
	eggs.y += bar.y
	foo.y = ham.y

if(foo.z > 5):
	bar.z = foo.z
	eggs.z += bar.z
	foo.z = ham.z

I would love to do something like this but I can’t figure out how to make it happen:

for axis in xyz:
	if(foo.axis > 5):
		bar.axis = foo.axis
		eggs.axis += bar.axis
		foo.axis = ham.axis

Thank you!!!

this wont be faster but should be working

var xyz = ["x","y","z"]

for axis in xyz:
	if(foo.get(axis) > 5):
		bar.set(axis, foo.get(axis))
		eggs.set(axis, eggs.get(axis) + bar.get(axis))
		foo.set(axis, ham.get(axis))

This is actually wrong!

Have a look at timothybrentwood answer below!

Yeah, it’s better than what I was doing though! Thank you!

This shouldn’t work on Vectors since they don’t have a get() method.

You can access x, y, and z using the [] operator:

for component in range(3):
    if foo[component] > 5:
        bar[component] = foo[component] 
        eggs[component] += bar[component] 
        foo[component] = ham[component] 

You are right … as statet here in the docs
