    f = open("Data.csv")
    for line in f.readlines():
        data = line.split(",")
        file[data[0]]= data[1]

def writedata(alldata1, filename):
    with open("./"+filename, "w")as csvfile:
        csvfile = csv.writer(csvfile, delimiter=",")
        csvfile.writerow("")
        for i in range(0, len(alldata1)):
            csvfile.writerow(alldata1[i])

def parse_data():

without seeing the data in 'Data.csv' (which should be named Data.html, if that what it contains, confusing otherwise)
it's difficult to answer this question, as we cannot run the code. In addition, always show the entire unaltered error traceback, your synopsis is really only marginally helpful.
