pprint(object, stream=None, indent=1, width=80, depth=None, *, compact=False)

In [1]: from sklearn.datasets import fetch_20newsgroups
   ...: from pprint import pprint
   ...: newsgroups_trian = fetch_20newsgroups(subset='train')
   ...: pprint(newsgroups_trian.target_names)
   ...:
['alt.atheism',
 'comp.graphics',
 'comp.os.ms-windows.misc',
 'comp.sys.ibm.pc.hardware',
 'comp.sys.mac.hardware',
 'comp.windows.x',
 'misc.forsale',
 'rec.autos',
 'rec.motorcycles',
 'rec.sport.baseball',
 'rec.sport.hockey',
 'sci.crypt',
 'sci.electronics',
 'sci.med',
 'sci.space',
 'soc.religion.christian',
 'talk.politics.guns',
 'talk.politics.mideast',
 'talk.politics.misc',
 'talk.religion.misc']

例图：

print(value, …, sep=’ ‘, end=’\n’, file=sys.stdout, flush=False)

In [2]: print(newsgroups_trian.target_names)
['alt.atheism', 'comp.graphics', 'comp.os.ms-windows.misc', 'comp.sys.ibm.pc.har
dware', 'comp.sys.mac.hardware', 'comp.windows.x', 'misc.forsale', 'rec.autos',
'rec.motorcycles', 'rec.sport.baseball', 'rec.sport.hockey', 'sci.crypt', 'sci.e
lectronics', 'sci.med', 'sci.space', 'soc.religion.christian', 'talk.politics.gu
ns', 'talk.politics.mideast', 'talk.politics.misc', 'talk.religion.misc']
