I am trying to load the help on each method into a QTextEdit in PyQt4

how can I have this variable hold help on a method, example:
data = os.system('python -c "import sys; help(sys.path)"')

but data value contains 0

got some success but the text is not properly formatted any help would be appreciated

data = os.popen('python -c "import sys; help(sys.path)"').read()

now data stores value like the below but not formatted..

is this possible to do how I am trying to do

    def outputHelp(self):
        ### module ###
        module = ""
        items = self.searchListView.selectedIndexes()
        for item in items:
            module = str(item.data().toString()).split(":")[0]
        method = ""
        items = self.methodListView.selectedIndexes()
        for selItem in items:
            method = str(selItem.data().toString())
        __import__(module)#,globals={}, locals={}, fromlist=[], level=-1)
        # self.methodListView.
        data = os.popen('python -c "help('+module.method+')"').read()
