python进度条

本文主要是介绍python进度条，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

def progress(index0,rowmax0,msg='',skip=0,refresh_time=1,bar_len=20):
    """
    展示进度条的自定义函数，接收6个参数
    index0：当前的进度序号
    rowmax0：总进度序号
    msg：进度条附带显示的信息
    skip：进度条从什么序号开始，默认是0，适用于中断后从断点继续工作的场合
    refresh_time：多长时间刷新一次进度条，默认是1秒
    bar_len：进度条长度，默认是20
