Printing a text tree in python

Question

How would you print a tree in python so it looks like the following:

          /\
         /  \
        /    \
       /      \
      /        \
     /          \
    /            \
   /              \
  /                \
 /                  \

The height should be changeable.

def tree(n):
    treeStr = ""
    for i in range(0,n):
        level = " "*(n-i) + "/" + " "*(2*i) + "\\"
        treeStr += level.center(n+1) + "\n"
    print(treeStr)

tree(10);
