python下载文件时显示下载进度的代码详解编程语言

将这段代码放入你的脚本中，类似：urllib.urlretrieve(getFile, saveFile, reporthook=report)

第三个参数如下面的函数定义report，urlretrieve下载文件时会实时回调report函数，显示下载进度

def report(count, blockSize, totalSize): 
    percent = int(count*blockSize*100/totalSize) 
    sys.stdout.write("/r%d%%" % percent + ' complete') 
    sys.stdout.flush() 
   
sys.stdout.write('/rFetching ' + name + '.../n') 
urllib.urlretrieve(getFile, saveFile, reporthook=report) 
sys.stdout.write("/rDownload complete, saved as %s" % (fileName) + '/n/n') 
sys.stdout.flush()
