Python projection but got an array

Grasshopper

I am trying to project all points of the circle onto the brep, but I got an array and I do not know how to access the array to select the first projected.
What am I doing wrong?
Thanks in advance for your response.

it seems that each projection of yours will produce two points.
so you just need to subscribe once more
projPoint_listPt[0][0] and projPoint_listPt[0][1]

If you want to pick a nearer one, you can use sort.

ss=sorted(projPoint_itemPt,key=lambda P:(prPoints_listPt[i]-P).Length) #sort using the distance
projPoint_itemPt=ss[0]  #pick the nearest point

By the way, P and v are exactly same in the below code

for i,v in enumerate(listPt):
    P=listPt[i]

So you can write

for v in listPt:
    P=v

Also,

for i, v in enumerate(listPt):
    P=listPt[i]
    Q=anotherlist[i]

is equilavent to

for v,q in zip(listPt,anotherlist):
    P=v
    Q=q
