本文实例讲述了Python调用命令行进度条的方法。分享给大家供大家参考。具体分析如下:

关键点是输出'\r'这个字符可以使光标回到一行的开头,这时输出其它内容就会将原内容覆盖。

import time
import sys
def progress_test():
  bar_length=20
  for percent in xrange(0, 100):
    hashes = '#' * int(percent/100.0 * bar_length)
    spaces = ' ' * (bar_length - len(hashes))
    sys.stdout.write("\rPercent: [%s] %d%%"%(hashes + spaces, percent))
    sys.stdout.flush()
    time.sleep(1)
progress_test()

希望本文所述对大家的Python程序设计有所帮助。
