[Python] Print input and output in table

Print the input and output in a table using prettyTable.

from prettytable import PrettyTable
import collections    

def printTableResult(variables, count):
    inputList = collections.defaultdict(list)
    outputList = collections.defaultdict(list)
    resultTable = PrettyTable()

    for variable in variables:
        if variable.type == "input":
            inputList[variable.variable_id] = variable.values
            length = len(variable.values)
        elif variable.type == "output":
            outputList[variable.variable_id] = variable.values

    logIdColumn = []
    outputSepColumn = []
    for i in range(count):
        logIdColumn.append(i)
        outputSepColumn.append("")
    resultTable.add_column("Run ID", logIdColumn)

    for each in inputList:
        column = []
        for i in range(count):
            column.append(inputList[each][i].value)
        resultTable.add_column(each,column)
    resultTable.add_column("output", outputSepColumn)
    for each in outputList:
        column = []
        for i in range(count):
            column.append(outputList[each][i].value)
        resultTable.add_column(each, column)

    print(resultTable)
