First, let's take a look at the NumPy and SciPy module documentation. What will be described here is not a topic specific to data analysis, but more of a general Python item.
The following code prints the descriptions of subpackages for NumPy and SciPy:
import pkgutil as pu
import numpy as np
import matplotlib as mpl
import scipy as sp
import pydoc
print "NumPy version", np.__version__
print "SciPy version", sp.__version__
print "Matplotlib version", mpl.__version__
def clean(astr):
s = astr
# remove multiple spaces
s = ' '.join(s.split())
s = s.replace('=','')
return s
def print_desc(prefix, pkg_path):
for pkg in pu.iter_modules(path=pkg_path):
name = prefix + "." + pkg[1]
if pkg[2] == True:
try:
docstr = pydoc.plain(pydoc.render_doc(name))
docstr = clean(docstr)
start = docstr.find("DESCRIPTION")
docstr = docstr[start: start + 140]
print name, docstr
