ModuleNotFoundError: No module named 'p5'

When I try to run one of the programs it states that it can't find the to import module p5. Could anyone clarify what I'm doing wrong?

Project link in README is broken

The link to https://p5py.github.com/ is 404.

Might have meant to link to

• https://p5py.github.io/
• https://github.com/p5py/
• http://p5.readthedocs.io/

...or all of them.

Vector example — drawing arrows

This is not an issue :-)

Perhaps could you put this snippet in examples directory ?
Feel free to modify it as you like

# Drawing Arrows

v = Vector(0, 100)

def setup():
    size(800, 600)
    title("Rotating Arrow")

def line_vect(v1, v2):
    line((v1.x, v1.y), (v2.x , v2.y))

def drawArrow(v1, v2):
    vs = v2 - v1
    mag, angle  = vs.magnitude, vs.angle
    line_vect(v1, v2)
    with push_matrix():
        rotate(angle)
        line((mag, 0), (mag - 15, 6))
        line((mag, 0), (mag - 15, -6))

def drawAxes():
    drawArrow(Vector(0,0), Vector(0, -250))
    drawArrow(Vector(0,0), Vector(250, 0))

def draw():
    background(0, 0, 0, 5.0)
    stroke(0, 223, 0)
    translate(width/2, height/2)
    drawAxes()
    stroke(255, 0, 0)
    drawArrow(Vector(0, 0), v)
    v.rotate(ang)
