how to call the x component of a vector in python

how would you write the x component of :
a = sphere(pos = vector(1,2,3)) *example

That doesn't look like correct Python to me... what module is this?

vpython

Isn't the x-component this:

a = sphere(pos = vector(1,2,3))

a = sphere(pos = vector(1,2,3))

no i mean, what is the line of code that calls the x component of that vector

a.pos[0]? I'm assuming sphere is a class

never heard of vpython, I'd have just used a numpy array

that doesnt work unfortunately, a typeerror forms:
"'vpython.cyvector.vector' object is not subscriptable"

ugh.

It must have its own method for calling the component then

it seems so

What about print()

See the bottom of the documentation page:

wouldnt that print out all of the components instead of only the x component

I've never used vPython, but doesn't the paragraph headed "Vectors" on that site indicate that if a is a vPython vector object then you may refer to its components as a.x, a.y, a.z etc?

I was looking forever and figured it out through trial and error. VPython uses 'vector_name.x' to call on the x component and so on.

# Define a vector
my_vector = vector(1, 2, 3)

# Access individual components
x_component = my_vector.x
y_component = my_vector.y
z_component = my_vector.z
