本文实例讲述了python下载文件时显示下载进度的方法。分享给大家供大家参考。具体分析如下:

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()

希望本文所述对大家的Python程序设计有所帮助。
