实际就是’\r’
import sys, time
import os
class ProgressBar:
def __init__(self, count = 0, total = 0, width = 50):
self.count = count
self.total = total
self.width = width
def move(self):
self.count += 1
def log(self):
sys.stdout.write(' ' * (self.width + 9) + '\r')
sys.stdout.flush()
progress = self.width * self.count / self.total
sys.stdout.write('{0:3}/{1:3}: '.format(self.count, self.total))
sys.stdout.write('#' * int(progress) + '-' * int(self.width - progress) + '\r')
if progress == self.width:
sys.stdout.write('\n')
sys.stdout.flush()
bar = ProgressBar(total = 100,width=os.get_terminal_size().columns-9)
for i in range(100):
bar.move()
bar.log()
time.sleep(0.1)
