#=========實現列印進度條函數==========import sysimport timedef progress(percent,width=50):    if percent >= 1:        percent=1    show_str=(‘[%%-%ds]‘ %width) %(int(width*percent)*‘#‘)    print(‘\r%s %d%%‘ %(show_str,int(100*percent)),file=sys.stdout,flush=True,end=‘‘)#=========應用==========data_size=1025recv_size=0while recv_size < data_size:    time.sleep(0.1) #類比資料的傳輸延遲    recv_size+=1024 #每次收1024    percent=recv_size/data_size #接收的比例    progress(percent,width=70) #進度條的寬度70
