converting dataframe from Hex to binary in using python
If I understood, in column 1 you have 00, column 2 : 55, ...
If I am right, you first need to concat three columns in a string value = str(col1)+str(col2)+str(col3) and then use the method to convert it in binary.
I am pretty new to Python and pandas library, i just learned how to read a csv file using pandas. 
my data is actually raw packets i captured from sensor networks, to analyze corrupt packets.
what i have now is, thousands of rows and hundreds of columns, literally, and the values are all in Hex. i need to convert all the values to binary with trailing zeros.
i am at lost on how to accomplish that once i have read the CSV file successfully using pandas.
I'd appreciate every kind of help, even a simple direction.
here is my sample data:

00 FF FF 00 00 29 00 89 29 41 88 44 22 00 FF FF 01 00 3F 06 55 55 55
  55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55 55
