自学教程：Python制作运行进度条的实现效果(代码运行不无聊)

import sysimport time# 普通进度条# 在代码迭代运行中进行统计计算，并使用格式化字符串输出代码运行进度def progress_bar(): for i in range(1, 101): # 1-100  print("/r", end="") # /r 表示将光标的位置回退到本行的开头位置  print("Download progress: {} {}%".format("▋" * (i // 2), i), end="")  sys.stdout.flush()  # sys.stdout.flush()的作用就是显示地让缓冲区的内容输出。  time.sleep(0.02)progress_bar()

import timescale = 50start = time.perf_counter() # 返回性能计数器的值（以秒为单位）for i in range(scale + 1): progress_bar = "▋" * i completion_ratio = (i / scale) * 100 dur_time = time.perf_counter() - start print("/rDownload Process：{:^3.0f}% [{}] {:.2f}s".format(completion_ratio, progress_bar, dur_time),end = "") time.sleep(0.1)

from time import sleepfrom tqdm import tqdm# 里面传入一个可迭代对象for i in tqdm(range(1, 101)): # 模拟你的任务 sleep(0.05)sleep(0.5)

import timeimport progressbardef custom_len(value): # These characters take up more space characters = {  '进': 3,  '度': 3, } total = 0 for c in value:  total += characters.get(c, 1) return totalbar = progressbar.ProgressBar( widgets=[  '进度: ',  progressbar.Bar(marker='#', left='|', right='|'),  ' ',  progressbar.Counter(format='%(value)02d/%(max_value)d'), ], len_func=custom_len,)for i in bar(range(100)): time.sleep(0.05)
