python进度条实现的几种方法

一、普通进度条(time实现)

import time

def progress_bar():
    for i in range(101):
        print(f'\rProgress: {"#" * i}{"." * (100 - i)} {i}%', end='')
        time.sleep(0.1)

if __name__ == '__main__':
    progress_bar()

展示结果:

 

二、带颜色、样式的进度条(colorama

from colorama import init, Fore, Back, Style
import time

def colored_progress_bar():
    init(autoreset=True)
    for i in range(101):
        percentage = Fore.GREEN + f'{i}%' + Fore.RESET
        filled_length = int(i // 2)
        bar = Back.WHITE + Fore.BLUE + '#' * filled_length + Fore.RESET + Back.RESET + '.' * (50 - filled_length)
        print(f'\r{bar} {percentage}', end='')
        time.sleep(0.1)

if __name__ == '__main__':
    colored_progress_bar()

展示结果:

 

三、简单的进度条工具包实现(tpdm)

from tqdm import tqdm
import time

def tqdm_progress_bar():
    for i in tqdm(range(100)):
        time.sleep(0.1)

if __name__ == '__main__':
    tqdm_progress_bar()

展示结果:

 

四、带一点动画效果的进度条(alive_progress)

import time

from alive_progress import alive_bar

items = range(100)

with alive_bar(len(items)) as bar:
    for item in items:
        bar()
        time.sleep(0.1)

展示结果:

 

五、可视化进度条(tkinter+time)

import tkinter as tk
import time
from tkinter import ttk

def gui_progress_bar():
root = tk.Tk()
root.title('进度条示例')

progressbar = ttk.Progressbar(root, orient='horizontal', length=400, mode='determinate')
progressbar.pack(pady=20)

root.update()

for i in range(101):
progressbar['value'] = i
root.update()
time.sleep(0.1)

root.destroy()

if __name__ == '__main__':
gui_progress_bar()

展示结果:
