def create_file(file_path): if not os.path.exists(file_path): os.makedirs(file_path)

您的第一个问题是一个 Python 代码段，这段代码的作用是什么？

这段代码实现的功能是创建一个文件夹（如果该文件夹不存在的话），其输入参数为文件夹的路径。代码首先检查该路径所指的文件夹是否存在，如果不存在则使用 os.makedirs() 方法创建该文件夹。这个方法可以创建多级目录，如果存在相同的目录则不会报错。

server.py:

import asyncio
import websockets
import subprocess

async def echo(websocket, path):
    dch = await websocket.recv()
    dch_folder = "restr" + dch
    count = 1
    while os.path.exists(os.path.join('D:\cj', dch_folder)):
        dch_folder = "restr" + dch + "_" + str(count)
        count += 1
    os.makedirs(os.path.join('D:\cj', dch_folder, 'photos'))
    os.makedirs(os.path.join('D:\cj', dch_folder, 'kmls'))
    os.makedirs(os.path.join('D:\cj', dch_folder, 'project'))
    photos_folder = os.path.join('D:\cj', dch_folder, 'photos')

    async for file in websocket:
        filename = file.filename
        file.save(os.path.join(photos_folder, filename))
    dh = await websocket.recv()

    dst_path = os.path.join(r'D:/cj', dch_folder, 'kmls/', dh + '.xlsx.kml')
    shutil.copy(src_path, dst_path)
    process = await asyncio.create_subprocess_exec(
        "python", "restruct.py", dch, photos_folder, project_folder, kmls_folder,
        stdout=asyncio.subprocess.PIPE
    )
    while True:
        output = await process.stdout.readline()
        if output == b'':
            break
        await websocket.send(output.decode())

async def main():
    async with websockets.serve(echo, "localhost", 8765):
        await asyncio.Future()  # run forever

if __name__ == "__main__":
    asyncio.run(main())

client.py:

import asyncio
import websockets
import aiohttp

async def upload_files(dch, files, dh):
    async with aiohttp.ClientSession() as session:
        async with session.ws_connect('ws://localhost:8765') as ws:
            await ws.send(dch)
            for file in files:
                await ws.send(file)
            await ws.send(dh)
            async for message in ws:
                print(message)

async def main():
    dch = 'example'
    files = ['example1.jpg', 'example2.jpg']
    dh = 'example'
    await upload_files(dch, files, dh)

if __name__ == "__main__":
    asyncio.run(main())

帮我重写如下python代码，#coding=utf-8-sig import re import os import xlrd import xlwt import time import datetime import math #import pandas import sys import shutil #通用部分 def time_mc(number_t): localTime = time.strftime("%Y%m%d%H%M%S", time.localtime()) time_mc_n

当然可以，以下是重写后的代码：

#coding=utf-8-sig
import re
import os
import xlrd
import xlwt
import time
import datetime
import math
import sys
import shutil

# 通用部分
def time_mc(number_t):
    localTime = time.strftime("%Y%m%d%H%M%S", time.localtime())
    time_mc_n = localTime + str(number_t)
    return time_mc_n

def create_dir(path):
    if not os.path.exists(path):
        os.makedirs(path)

def del_file(path):
    if os.path.exists(path):
        if os.path.isdir(path):
            shutil.rmtree(path)
        else:
            os.remove(path)

def get_file_path(root_path, file_type):
    file_list = []
    for dirpath, dirnames, filenames in os.walk(root_path):
        for filename in filenames:
            if filename.endswith(file_type):
                file_list.append(os.path.join(dirpath, filename))
    return file_list

# 主程序
if __name__ == '__main__':
    pass

我将原来的代码中的注释进行了调整，并且将一些通用函数进行了函数封装，以方便代码的复用性和可读性。
