python ftp上传文件（带进度条显示）

想法

用python写个ftp上传文件的功能，想要实时看到上传进度，进度条ui部分，使用python的tkinter库实现。

最终效果

python代码

from ftplib import FTP            
import sys,getpass,os.path    

import tkinter as Tkinter
from tkinter import ttk
import time
import threading


HOST = '192.168.1.8'  # ftp地址
PORT = 21
TIMEOUT = 30  # 超时时间
USER_NAME = 'linxinfa'  # ftp账号
PASS_WORD = '123456'	# ftp密码
BLOCK_SIZE = 8192		# 每帧上传的数据大小

file_name = ''			# 上传的文件名，ui部分显示用
file_size = 0			# 文件总大小，计算进度时用
upload_size = 0			# 已上传的数据大小，计算进度时用
bar = None				# 进度条对象
