Installation

Use the package manager pip to install taxopedia.

pip install taxopedia

Getting Started

import taxopedia

# create a tree... and get a bag of parsed biota boxes!
tree, bag = taxopedia.search("Bears", comprehensive=True)

# pretty print the tree
print(tree.pretty())

# export multiple formats
tree.to_txt("tree_Ursidae.txt")    # plain-text dendrogram
tree.to_html("page_Ursidae.html")  # diagram with images
tree.to_csv("table_Ursidae.csv")   # filled-out tabular data

Tree Manipulation

# take a clone of a tree (to prevent mutation)
cutting = tree.clone()

# finding a node
bears = cutting.find("Ursidae")

# trim cousins (other children of all parents)
bears.exclude_cousins()

# return to the root (topmost parent)
cutting = bears.root()

# re-root the tree
bears = cutting.from_pov("Ursidae")

Saving and Loading Progress

# save the biota bag (so you don't have to scrape it again!)
taxopedia.dump_bag("bag_Ursidae.json", bag)

# loading the biota bag
bag = taxopedia.load_bag("bag_Ursidae.json")

# how to get a tree from a bag
tree = taxopedia.make_tree(bag)
