Python 脚本 进度条显示 2 样式美化

tqdm 增加 bar_format , ascii 配置

进度条背景样式

ascii="-━" 需两个字符

• 首字符 - 为背景
• 尾字符 ━ 为实际进度

效果

python 执行命令日志同一行刷新

• 加入\r desc=f'\rUploading {os.path.basename(local_path)}'

import paramiko
from tqdm import tqdm
import os

# SSH 连接信息
hostname = 'your_linux_server_ip'
port = 22
username = 'your_linux_username'
password = 'your_linux_password'


# 远程目标路径
remote_path = '/home/target_path/file.txt'
base_path = r'E:\source_path'

# 使用 os.path.join() 拼接路径
local_path = os.path.join(base_path, filename)

# 远程目标路径
remote_path = '/root/' + filename

# 获取本地文件大小
local_file_size = os.path.getsize(local_path)

# 建立 SSH 连接
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname, port, username, password)

# 使用 SFTP 协议传输文件
sftp = ssh.open_sftp()

# 进度条样式
bar_format = "{desc}: {percentage:3.0f}%|{bar:42}| {n_fmt}/{total_fmt} [{elapsed}<{remaining}, {rate_fmt}]"


# 显示进度条
