6行Python代码实现进度条效果（Progress、tqdm、alive-progress​​​​​​​和PySimpleGUI库）

pip install progressbar2

import time

# 加上进度,就是将range(N)放到ProgressBar()中
for i in p(range(N)):
  #每次延时0.1S
  time.sleep(0.1)

    progressbar.Counter(format='%(value)02d/%(max_value)d'),
  ],
  len_func=custom_len,

pip install alive-progress

from alive_progress import alive_bar
