1、进度条

import timedef func(size,total_size):    val = int(size/total_size * 100)    time.sleep(0.1)    print('\r%s%%|%s' %(val,"#"*val,), end='')for i in range(101):    func(i,100)

2、计算文件大小

import ossize = os.stat(r'D:\sylar\s15\day31\1.进度条.py').st_sizeprint(size)

3、修改文件名称

import osimport shutilos.rename('a.text','b.txt')#py2 + win：报错shutil.move('c.txt','a.txt')

4、图标

v = '\ue056'print(v)

5、client
