import time
import random


def progress_bar():
    for i in range(1, 300):
        print("Download progress: {}%: ".format(i), "▋" * (i // 2), f'{i}/100')
        time.sleep(random.random())

def progress_bar():
  for i in range(1, 101):
    print("\r", end="")
    print("Download progress: {}%: ".format(i), "▋" * (i // 2), end="")
    sys.stdout.flush()
    time.sleep(0.05)

三(带时间):

import time

scale = 50
print("执行开始，祈祷不报错".center(scale // 2,"-"))
start = time.perf_counter()
for i in range(scale + 1):
  a = "*" * i
  b = "." * (scale - i)
  c = (i / scale) * 100
  dur = time.perf_counter() - start
  print("\r{:^3.0f}%[{}->{}]{:.2f}s".format(c,a,b,dur),end = "")
  time.sleep(0.1)
 
print("\n"+"执行结束，万幸".center(scale // 2,"-"))
