python - Creating multiple lists within a single Main List - Matplotlib table

Question

Hi

I am having problems with creating a matplot lib table using python.

The example i have been following : http://matplotlib.sourceforge.net/examples/pylab_examples/table_demo.html

My data :

I have two for loops where in the first For loop i get the Protocol Name and in the second for loop i get the module name. I need the data to be like this for pushing it into the matplotlib table.

data = [[  66386,  174296,   75131,  577908,   32015],
        [  58230,  381139,   78045,   99308,  160454]]

Instead my Data is like this

data = [[  66386,  174296,   75131,  577908,   32015,
          58230,  381139,   78045,   99308,  160454]],

My Code :

ProtocolList = [DHCP , PPOEE ,WANe ]
  passList = []

for protocol in protocolList:

           # Comment- modules= [ frag,app,scale] This below line gets all the module names

           moduleNames = d[ protocol ].getModuleNames()  

            for module in moduleNames:

                 # This line gets all the passes for each module 
                 numberOfPasses = d[protocol].getModule(module)[1]                 
                 passList.append(numberOfPasses)
 print passList


My Output : [6, 3, 1, 2, 22, 3, 3, 4, 13, 0, 7, 27, 5, 8, 4, 8, 1, 7, 6, 13, 7, 9, 23, 3, 4,
1, 7, 4, 0, 22, 8, 6, 7, 27, 4, 3, 1, 3, 1, 12, 3, 6, 8, 2, 9, 19, 3, 6, 2, 22,
2, 8, 4, 3, 0, 7, 10, 27, 5, 8, 4, 1, 7, 6, 13, 1, 9, 23, 3, 4]

Its Combining all the passes all modules in one list where i want the passes for each module to go into individual lists so i can put it use it for the matplotlib table data

So basically i have to put the pass and fail values in individual lists

like this [[ pass] [fail] [pass] [fail] ] Instead its like this [[ pass , pass , fail , fail ]]

You're using a single append statement. Since you're doing that it's only ever going to append to a single list.

passList.append( d[ protocal].getModule(module)[1] for module in moduleNames )

that'll create a new list for each protocal which isn't what you want. One sec...

from collections import defaultdict
passList = defaultdict(list)

for module in moduleNames:
    passList[ module ].append( d[ protocol].getModule( module )[1] )

print passList.values()
