[Discuss-gnuradio] Problems using gnuradio blocks

[Alysson Menezes]

            Hello everybody. I was trying to use the gnuradio complex_to_float () block just to understand its functioning. Unfortunately, the conversion not happened and apparently there was no problem. The code is below. What's the problem with this so simple code?
            One more thing, it would be so helpful a dictionary with all the gnuradio blocks and usage examples. Examples are fundamental to help us reach a good level to be able to contribute for the gnuradio project, without waste so much time. Thank you very much.

#!/usr/bin/env python

from gnuradio import gr, eng_notation, gru, window, blks
from gnuradio import audio
from gnuradio import usrp
from gnuradio.eng_option import eng_option
from optparse import OptionParser
from gnuradio import gr_unittest


class my_graph(gr.flow_graph):

    def __init__(self):
    gr.flow_graph.__init__(self)
   
    self.data = "" 2, 3)
    self.converte = gr.complex_to_float()
    self.src = "" (self.data)
    self.vetor2 = gr.vector_sink_f ()

    raw_input (self.data)
   
    self.connect (self.src, (self.converte,0))
    self.connect ((self.converte,0), self.vetor2)
   
    self.rst = self.vetor2.data ()

    raw_input (self.rst)



if __name__ == '__main__':
    try:
        my_graph().run()
    except KeyboardInterrupt:
        pass
