Python:xml.etree.ElementTree.parse输出文本并阻止输出流

我尝试通过HTTP请求向服务器获取一些XML，然后使用XML.etree.ElementTree.parse解析XML

但是，由于某些原因，程序在控制台中输出整个XML，并在之后阻塞输出流

如果你能帮我解决这个问题，我将不胜感激。我发布了用于测试的代码

import requests
import xml.etree.ElementTree as etree
import sys

TOPCODER_BASE_URL = 'http://community.topcoder.com/tc?module=BasicData&c=dd_round_results&rd='

def getWebsite(url):
    response = requests.get(url)
    return response.text

def getTopCoderRound(rnd):
    response = getWebsite(TOPCODER_BASE_URL + rnd)
    return response

def loadData(outputFile):
    handleFile = sys.argv[2]

    f = open(handleFile, 'r')
    outputFile.write ("#opened file")
    users = []
    for line in f:
        users.append(line)

    outputFile.write("#added users")
    return sys.argv[1], users

outputFile = open('results.txt', 'w')

outputFile.write("reached this point")

roundNo, users = loadData(outputFile)
outputFile.write("#loaded data")
xml = getTopCoderRound(roundNo)
outputFile.write("#read xml")
tree = etree.parse(xml)

outputFile.write("reached this point")
root = tree.getroot()

函数应该将文件作为参数，而不是字符串。这就解决了问题
