Prettyprint to a file?

问题

I'm using this gist's tree, and now I'm trying to figure out how to prettyprint to a file. Any tips?

回答1:

What you need is Pretty Print pprint module:

from pprint import pprint

# Build the tree somehow

with open('output.txt', 'wt') as out:
    pprint(myTree, stream=out)

回答2:

If I understand correctly, you just need to provide the file to the stream keyword on pprint:

with open(outputfilename,'w') as fout:
    pprint(tree,stream=fout,**other_kwargs)
