        Process(target=bMusic.download, args=(53535187,"张恒-冰雨")).start()

下载文件有以下方法：

方法一：

urllib.urlretrieve(url, savepath)  <span style="font-family: Arial, Helvetica, sans-serif;">#url:源文件地址 savepath:下载保存路径</span>

代码示例：

import urllib
    
    urllib.urlretrieve('http://music.baidu.com/data/music/file?link=&song_id=1128053', 'C:/BingYu.mp3')

方法二：

f = urllib2.urlopen(url)  #url:源文件地址
    data = f.read()  
    with open(savepath, 'wb') as code:  #savepath:下载保存路径
        code.write(data)

代码示例：

import urllib2
    
    f = urllib2.urlopen('http://music.baidu.com/data/music/file?link=&song_id=1128053')  
    data = f.read()  
    with open('C:/BingYus.mp3', 'wb') as code:  
        code.write(data)

方法三：

#!/usr/bin/env python  
    #-*- coding: UTF-8 -*-  
    import requests
    
    req = requests.get('http://music.baidu.com/data/music/file?link=&song_id=1128053'.decode('utf-8'))  
    with open('C:/冰雨.mp3'.decode('utf-8'), 'wb') as code:  
        code.write(req.content)
