python实现进度条和百分比同时显示

python中同时打印进度条和百分比

仅打印进度条:

import sys,time
for i in range(100):
    sys.stdout.write('>')
    sys.stdout.flush()
    time.sleep(0.1)

效果:

 

打印百分比:

import sys,time
for i in range(100):
    sys.stdout.write('\r%s%%'%(i+1))
    sys.stdout.flush()
    time.sleep(0.1)

 效果:

打印进度条和百分比

import sys,time
for i in range(100):
    k = i + 1
    str = '>'*i+' '*(100-k)
    sys.stdout.write('\r'+str+'[%s%%]'%(i+1))
    sys.stdout.flush()
    time.sleep(0.1)

 

让进度条短一些:

import sys,time
for i in range(100):
    k = i + 1
    str = '>'*(i//2)+' '*((100-k)//2)
    sys.stdout.write('\r'+str+'[%s%%]'%(i+1))
    sys.stdout.flush()
    time.sleep(0.1)

效果:
