python3-kdtree-dbg 0.7.1+git20101123-5build1 (armhf binary) in ubuntu focal

 A container implementing k-dimensional space sorting using a kd-tree. It:
 .
  - supports two- to six-dimensional spaces
  - can store any data structure
  - provides standard find as well as range queries
  - has amortised O(lg n) time (O(n lg n) worst case) on most operations
    (insert/erase/find optimised) and worst-case O(n) space
  - provides means to rebalance and thus optimise the tree
 .
 This package contains the extension built for the Python 3 debug interpreter.
